The Most Famous programming languages in 2021 and their uses

Do you know how many smart devices we handle every day? Are they just computers, mobile phones, home appliances (TV-washing machine-air conditioning), or calculators that students use every day?


What about digital devices found in hospitals (cardiac devices - anesthesia - radiology - analysis, etc.), factories (digital meters - controllers, etc.), banks (surveillance tools - digital tanks - counting and raising tools, etc.).

All of these devices we need to talk to every day, and like us humans we need common languages that we can communicate and the other side understands.


Smart machines and processor-based computers need someone to communicate with them, telling them what specifically we want in a language they understand... Here comes the role of programming languages.


What is programming?

In short, programming is the process of preparing a set of instructions that we give to any computer, in order to perform a particular task or obtain a predetermined result.

A computer or computer of all kinds is a very stupid machine, you don't know how to behave at all, and you need us to direct and give clear specific instructions.

Imagine describing to someone how to do a cooking you love... But this blind person doesn't see, then you'll describe it all step by step.

You'll tell him every move he makes in the exact order until he gets every ingredient he'll use for cooking, every tool he'll rely on, and then how to set these ingredients up until the cooking comes out ready for you.

And because there are so many devices or computers, there are also different ways to communicate with them... And that's where the different programming languages come in.


There are specific methods of writing these instructions... And that's where the programming languages came in.


What is a programming language?


A programming language is a tool that we use to give a computer the instructions it needs to perform a particular software task... In a simpler sense, it's a way to communicate with any particular computer or device to tell it how to act to give us what we want.

The computer is powered by electricity, so it only understands "does the electricity run (On) or cut off (Off)," or in other words only the binary numbers (1 and 0)... The one I studied in modern physics in high school.


Ordinary humans will be difficult to understand and write binary numbers, especially if the devices they handle consist of complex circuits.

That is why there is a need for a way in which we can transform the way we human beings speak into a language that the computer understands, without having to use binary numbers directly... And that's the programming language in a nutshell.


As has been the case since ancient times when man learned the basic words, then different languages emerged and evolved and changed to facilitate life... Different programming languages have also emerged to facilitate the handling of computers.


You can watch this simple video until the picture becomes clearer to you:

Code terms you should know.

There are a bunch of common definitions you'll meet as you look for the most popular programming languages or for programming in general... Let me give it to you in an easy, simple way.


1.Text coding (Syntax)

Each language has agreed rules (such as grammar in Arabic - the Grammar in English) that help us write useful sentences that anyone understands.

Each programming language also has rules, an agreed way to be written so that any programmer can easily understand and use it anywhere in the world... These rules are Syntax.


2.Classification of programming language in terms of hardware handling

There are many classifications of programming languages, perhaps the most important of which is to determine how close any language is to the way a computer understands codes or so-called machine language.


There are two types of languages in this classification:


Low Level Languages: Languages that are very close to machine language... Such as C, Assembly, and others.


High Level Languages: Languages that move away from machine language and approach our normal language... Like Java, Python, Javascript and others.


3. Classification of programming languages in terms of modus operandi

This classification is based on how the language deals with instructions and converts them into binary codes for computer understanding. There are two types of programming languages in this classification:


• Compiled Programming Languages: These languages themselves translate instructions and convert them once into codes.

Languages like C, C++, C # and Go... All are translated languages, and are widely used.


• Interpreted Programming Languages: These languages rely on an interpreter or interpreter to convert instructions into computer-understood codes... The programmer is not responsible for this process.

Languages such as Javascript and Python are interpreted languages.


4. Programming style

There are many ways in which programming is done in different languages... What is meant here by style is a common and similar method between languages... Such as writing methods or rules common to ordinary languages of the same origin (e.g. English and French).


The most important of these methods are:


1. Object-oriented programming-OOP: In this method, any element of language is treated as something that we must define and then determine how to deal with.

This type of programming you find in languages like Javascript and Java.


2. Structured programming: In this method, elements of language are treated as a set of consecutive steps or instructions.


This type of programming is found in all C-family languages and GO-language... most low-level languages are treated in this way.

It's not important that these tariffs are now understood very deeply... All I just wanted was for you to recognize it so you understand that dealing with programming languages is very much like dealing with the normal languages we use every day.


 The Most Famous Programming Languages and Their Uses

1. JavaScript language

It is a software language dedicated to making web pages more interactive with visitors and has increased in importance and prevalence after the availability of several technologies that have increased speed between server and client such as ajax, and there are many similarities and differences between Java and JavaScript that have made each language their own.


JavaScript, also known as NodeJS, is the oldest language to appear in the first web browsers throughout history, and JavaScript has evolved from its inception to the present time - especially in 2015 and 2016 and beyond - to become one of the most popular languages.

This language is a high-level programming that allows you to execute complex functions on web pages in order to create more interactive pages, so it is one of the most important programming languages currently in use in 2021.

It also provides dynamic interaction on the site and is also used to provide web applications, providing games, interactive maps, 2D animation, 3D graphics, and multimedia management.


Top companies that rely on JavaScript language

Javascript has many uses, as I mentioned earlier; Any discloser this relies on other than the great potential offered by the Node.Js frame, that's why you find many giant companies relying on JavaScript such as:


1. Google: Google owns the Google Chrome browser, and also offers many products and services on websites, which rely mainly on Javascript.


2. Microsoft: I don't think you lose sight of Microsoft's Edge browser, which is one of the best internet browsers right now... Certainly, Microsoft needs JavaScript in its development. That's beyond the company's recent reliance on Node.Js in developing many of its services like Azure Cloud.


3. Paypal: E-banking and money transfer services leader PayPal relied from the outset on JavaScript to develop its site and services. After the advent of Node.Js, Baipal became heavily dependent on it for handling servers and customer databases.


4. Netflix: Netflix relies heavily on JavaScript, replacing Java with Node.Js to facilitate site development and increase efficiency and speed.


5. Facebook: If you try to stop JavaScript from working in your browser you won't be able to access your Facebook account.

And this shows you the scale of Facebook's reliance on JavaScript... Because of the importance of this language to Facebook, some programmers have developed the popular React.JS framework, which is widely used by web developers around the world.


HTML and CSS are not actual programming languages, as they do not contain the possibility of conducting logical processes such as (accounts - data recording) and others...


· HTML language

The word HTML is short for Hypertext Markup Language, and its Arabic translation (HTML) is a set of instructions that are used to structure web pages.

Any web page relies on HTML because it is responsible for determining:

§  headings, whether headings or subheadings.

§  lists (such as the main list you see at the top of the page).

§  Paragraph.

And other essential components of any web page, which are used and manipulated by other programming languages such as Javascript.

We can say that HTML is only the basic instruction that any browser relies on to understand the core content of different web pages, and then translate it and transform it into what they see on any site.


· CSS language

The word CSS is short for Cascading Style Sheets, translated in Arabic (stacked model pages)... In a simple sense CSS is a set of code that is used to coordinate pages.

What is meant here by the format is:

§  specify the distances between different lines and titles.

§  identify colors.

§  locate different items on any page.


You can say there's no web page without Html and CSS, so there's no web developer who doesn't know it very well.

3. SQL language

The word SQL is an acronym for Structured Query Language, translated in Arabic (Structural Query Language)... In a simple sense SQL is the language that is used to handle databases and manipulate them in different ways.

You can imagine the SQL looking like the instructions you give to the popular excel software to build tables and modify different columns and slots, add and scan information and perform various calculations.


SQL is very simple because its text coding (Syntax) is similar to the normal English we use (Select-Add-Delete-Create) and so on.


SQL will be used in almost all servers for sites and applications of all kinds and uses, making it the third most popular and used programming language.

4. Python Language

Python Python is one of the best programming languages every programmer learns and masters because it's easy to learn, and you can adapt to that language easily.


Python is an interpreted and versatile programming language, meaning you can use it for almost every task in the programming world like:

§  Web Development

§  Desktop Apps Software Building

§  Development of Telephone Applications

§  Gaming Development

§  Data analysis and collection  (Data analysis-Data science)

§  Writing different scraps to carry out specific and rapid tasks

§  Development of various AI applications

The importance of Python's language:

§  is easy to use, and simple, so every computer novice advises it.

§  as it is and despite its simplicity it is much needed in the labor market at the moment.

§  of the programming languages handle most databases easily and accurately.

§  Python.

§  works on all Windows and Linux operating systems as well as well-known Apple operating systems Macintosh.

§  Python is free, unlike most programming languages.

§  used to make many popular games and apps, including Civility IV, World of Tanks, Battlefield.


The reason Python has grown in popularity and usage since its 1991 development history by the genius programmer Guido van Rossum is its ease.

The script coding for this language is simple and easy, very similar to English, unlike many other programming languages... Which made Python attract a lot of beginners in the programming world


Top Python-based companies

You'd be surprised to know how many companies and apps you use every day that rely on Python:


1. YouTube: Yes, the world's largest video platform, and the second most popular search engine written and developed almost entirely in Python.

2. Instagram app: Instagram started with just 11 employees, and the entire app was initially written using one of Python's language frames which is Django.

3. Facebook Company: It is true that Facebook's app relies heavily on JavaScript, but according to Facebook itself, 21% of all codes and software that Facebook relies on are written entirely in Python.

4. Netflix Company: It's true that Netflix relies heavily on JavaScript, but the suggestion engine (Suggestions) that collects and analyzes user data and nominates different shows for them to watch is entirely Python-based.

5. Amazon: The world's e-commerce giant relies on Python language to build its popular proposal engine, which has been one of the most important reasons why Amazon has dominated the field in the world.

6. Uber: Uber relies heavily on Python's language to deliver its services, due to a lot of computations and data collection, which is why they chose this great language.

5. Java language

Java is also a versatile programming language, which is relied upon for many tasks especially in the development of high-level telephone, gaming and computational software applications.


Java is therefore commonly used in the development of applications for commercial companies in various fields, especially in the banking sector, various banking services, and online payments, which is why giant companies such as Amazon and eBay are highly reliant on Java.


The Java language also has the lion's share in developing Android applications, which is why it is so much needed in the global labor market.

The most important feature of Java is its efficiency in building graphics-based applications (GUI Apps - Graphic User Interfaces).


Java is also widely used in game development, for example, the popular game Minecraft based on Java. All this made Java become one of the most popular and used programming languages.

6. C# language

C-Sharp is a multi-use, global programming language, although it was launched in the late 2000s by a dedicated Microsoft staff.

And that's one of the reasons why this language is so popular, it's one of the best options programmers rely on in building desktop applications for the Windows operating system.


The distinctive feature of this language is that it has attempted to combine many features of other languages such as Java and C, which is why it is easy to learn for many programmers who have experience with those languages.

There are many companies around the world that rely on C-Sharp, especially in the field of games, because one of the world's most famous game engines, Unity, was built by C and C-Sharp.


if they do not know; The Unity engine is relied upon to build hundreds of games like the popular Pokémon Go and many more.

Of course that's not the only use because you can use that language in Windows operating system software.

7. PHP language

PHP is a scripting language used in web development, especially with regard to server handling.


The PHP language originally was a set of different applications written in Perl, which were then collected and arranged until it is what it is now.

PHP went through many stages of development beginning with its 1994 launch, and then rewritten again by other programmers in 1997.


Top PHP-based companies

§  Content management systems such as WordPress, Gumla and others.

§  Wikipedia.

§  Yahoo website.

8. TypeScript language

TypeScript is JavaScript with some modifications. JavaScript is dynamic, and that's what makes dealing with it lead to some errors sometimes.


For example, the programmer may easily mistake the types of variables (numbers or letters) for disruptions in different applications... This is why TypeScript has been developed.


TypeScript is a static, static, static language in which everything is defined and defined, so applications written through it are probably relatively larger but safer and problem-averse.


Developed by Microsoft, TypeScript was launched in 2012 and has since been used more widely every year, especially since it is very easy to learn, since many programmers know JavaScript well.


TypeScript is a practical example of developing and modifying programming languages in general, and the desire of experienced programmers to facilitate the programming and application development process and make it more efficient and less expensive as the moratorium passes.

9. Language++ C

C++ is a multi-use programming language developed in 1980 by giant programmer Bjarne Stroustrup in one of AT&T's renowned U.S. communications labs.


C++ is one of the most popular programming languages, because it was developed to be an extension of C, which is why it has the same uses and properties.


This language is used in object programming and is used to build complex games, graphical UI applications and large computer software, adopted by companies like Google and Facebook also in competitions where C++ experienced developers won the most.

10. C language

C is one of the most important programming languages of all time, as its development process is a watershed stage in the history of computer science in general.

The C language has been developed by one of the most famous and best computer scientists of all time, Dennis Ritchie in 1972, which many consider the godfather of programming.


The C language is the basis for the development of other programming languages that we talked about earlier, as Java, Python, C #, SQL and others were written and developed using C language.


Therefore, it is common among programmers to say, "Whoever understands the C language well can understand and learn any other language in several days."


C is very fast and accurate, because you control how the computer itself works in terms of processor and temporary memory (RAM).


Top C-based companies

1. Microsoft, Apple, and Google: rely on C language, as it is the basis for the development of Windows, Mac, IOS, Android and various software systems.

2. Adobe: Relies on C for developing its popular programs such as Photoshop and After Effects, and other programs that millions of people around the world rely on.

3. NASA: Relies on C to develop its own missile control programs, because C is very quick to execute commands.

11. Go language

Go is a multi-use language, developed by a specialist staff at Google in 2009, and its usage rate increases day by day.


Go is said to be the C language of the 20th century, it has been developed to perform almost the same tasks faster and easier, which is why many companies have relied on it since its launch.


Top companies that rely on Joe's language

§  Soundcloud Corporation

§  The Twitch company currently owned by Amazon

§  Uber Corporation

§  Google, which relies on it for a lot of tasks, is developing the cloud services provided by Google Cloud.


The Go language competes with both C and Java for speed, efficiency and reduced resources used to develop different applications and programs, but requires greater learning and use due to its modernity.

12. Kotlin language

Cotlin is one of the newest programming languages on this list, it was developed by a Russian staff at JetBrains beginning in 2010, and was officially launched in 2016.

Cotlin is a language that was originally developed to build phone apps on Android quickly and efficiently above Java and at a lower cost.


That's why Google announced in 2017 that it would rely on Cotlin for the development of Android itself, which was the main reason why the language was so popular, that it was started to be used by so many developers.


The most important companies that rely on Kotlin

§  Evernote: Owner of one of the most popular time management and task management apps.

§  Coursera Company: Owner of one of the most popular Coursat Online platforms.

§  Pinterest: which owns the popular Pinterest site and app in the world of social media, on which tens of millions of users rely.

§  Uber: Uber recently relied on Kotlin's language to develop its own app.






In the end...

Programming is a wonderful world full of new, every day there is a programmer trying to develop past tools and languages, adding properties and features to facilitate the programming process and reduce cost.


One of the most important obstacles standing in the way of new programmers is not knowing what the basics of programming are, how they can be learned from the best sources... So we are now working to provide comprehensive evidence to help you with that.


This information will make you properly established in the world of web development, opening the way for you in one of the most important disciplines in the world of programming.
