1. Java

Since its inception in the mid-90s, the Java language has consistently been one of the most popular programming languages. 30 years later, it is still a leading programming language: Java is indeed the native language of Android, the most widely used mobile platform in the world.

With 2.3 billion mobile devices running the Android operating system, Java is therefore very popular and many large companies are using Java to build their applications.

Java has reasons to be popular: it offers great portability (thanks to the Java virtual machine), independent of the platform. This means that Java can run on almost any system. It is also very scalable, which makes it popular with both large companies and rapidly growing start-ups.

Java is a statically typed language, so it’s fast and easy to maintain, with fewer bugs. It is also backward compatible, which means that older versions of the language still work fine, even when new versions are released. This helps keep an organization’s costs low, since there is no need to constantly rewrite code every time a new version is released.

Java is a popular language then and now, and its very large community guarantees its popularity in the future.

Codeur.com lists more than 16,000 freelance Java developers. Find the provider you need by posting your project for free on the platform.

2. Python

Python

Python was originally launched in 1991 and has taken a long time to gain its followers. Yet recent years have seen a boom in Python’s ranking, largely thanks to its possibilities in machine learning, data science, and artificial intelligence.

A high-level, versatile language, Python finds uses in building web applications, analyzing data, and developing algorithms. It has easy-to-use syntax and emphasizes code readability and simplicity, making it an ideal candidate for novice developers, especially those who want a career in artificial intelligence.

Python has a reputation for being very reliable and efficient. Its reliability and efficiency make it popular with both large companies and start-ups. Several Python libraries are available to developers: these libraries speed up various tasks in the field of building AI algorithms and binding to APIs. Additionally, it can be used to automate certain activities, including some time-consuming daily tasks.

Finally, Python can also be used for web development. This is because it is often used for web scraping and something that could take hours to code in PHP will only take a few minutes with Python. The Reddit website, for example, is built using Python.

The very active Python community is primarily responsible for the growth of this language. It offers best practice advice and troubleshooting solutions for beginners and experts alike.

For this reason, Python is known as the “fastest growing major programming language”. With applications in some of the fastest growing and most exciting technologies, developers who know Python will quickly find opportunities in Big Data, AI, robotics or cybersecurity. With these technologies becoming ubiquitous, it’s worth learning Python skills now.

3. C / C ++

Although it is not the easiest programming language for a beginner to learn, C ++ is essential in many areas: for example some operating systems are created in this programming language. You can find it in a wide variety of software, like web browsers, distribution systems, database software, video games, and many more.

C is a general purpose procedural programming language. Closely linked to the hardware, it enables data management and system programming at a low level. You can use it not only to create “ordinary” software, but also to develop programs at the driver or kernel level.

Over 10,000 C / C ++ developers are registered on Codeur.com. Find an available C / C ++ developer quickly by posting your project now.

4. C #

It is one of the oldest and most popular programming languages ​​thanks to its portability and early adoption by tech giants like Apple and Microsoft: known as “C-sharp”, it s ‘is in fact a derivative of the original language, developed in 2000 by Microsoft.

It is an object-oriented language, organized around objects rather than actions, and data rather than logic. Its characteristics are similar to those of Java, and C # is particularly good at creating desktop applications and Windows games. It can be used very well to develop web and mobile applications, and is often used for large enterprise applications, such as in the banking transaction processing industry.

IF your business is in the gaming industry (or is considering doing so), C # is a worthwhile investment, as 34% of mobile games are made using C #, as are virtual reality apps. It is notably present in games using Unity, such as “Temple Run Trilogy” or “Assassin’s Creed: Identity”.

That’s not all ! Even as a high-level programming language, C # is relatively easy to learn and more independent of a computer’s hardware architecture. Developers can also spot errors more easily in C #, because the code is checked by the framework before it becomes an application.

It also allows to acquire basic knowledge in other “C” languages, such as C ++, which then facilitates their eventual learning … Even if it offers an obvious path of learning and development, mastery of C # still takes more time and effort than Python.

5. Kotlin

Kotlin

Kotlin is number one for those who want to storm the Google Play Store. It was designated by Google as a primary technology for the development of Android. Note that it is executed on the Java virtual machine (see above) and that this language is not very obvious for someone who wants to take his first steps in programming….

It is therefore recommended to start by learning the Java language, before embarking on learning Kotlin.

6. Swift

Unlike the previous one, this language allows you to publish your applications in the AppStore: if you want to conquer this market, then you must start by learning the Swift language. It is the programming language for iOS, and was created by Apple itself!

It is the successor of the Objective-C and it is a very good choice for the neophyte. The future of the AppStore is written in Swift, and if you want to compete, then you have to learn this language.

8. Javascript

It’s a bit of a provocation that JavaScript ends this article: by far the most popular programming language on this list, it’s ubiquitous on the web, and in our lives.

JavaScript is used in particular in web development, to add interactivity to a site, whether in the form of games, buttons, dynamic styles, animations and forms. It was invented by Brendan Eich, co-founder of the Mozilla Project, the Mozilla Foundation, and the Mozilla Corporation. Since then, there are over 1.7 billion websites in the world and it is used on about 95% of them, which makes the reach of JavaScript extremely important.

Add to that the fact that JavaScript is very versatile and easy to learn, and you will see why it is such a popular programming language.

JavaScript is a basic language, to which is added great flexibility thanks to additional development tools that allow functionality to be unlocked with minimal effort. For example, you can easily integrate third-party content providers like Twitter and Facebook through an API.

Additionally, JavaScript is a cross-platform programming language that enables applications to be deployed on desktop and mobile platforms. It has become an essential element in today’s society, which favors mobile. JavaScript developers have access to a huge community of JavaScript enthusiasts who champion best practices in using the language, and who regularly come up with new ideas for its use. This community strives to ensure that JavaScript remains essential to the smooth functioning of the Internet for decades to come.
