The Top 5 Programming Languages

1. JavaScript

JavaScript is an essential programming language to learn because it’s everywhere and in everything. What’s particularly great about JavaScript is that it works on both the client and server side so you can build offline apps, desktop apps, native apps, and even run it on IoT (Internet of Things) devices. It’s the universal programming language of the web and will continue to be, so if you’re unsure what to learn this year, you can’t go wrong with learning JavaScript.

BONUS TIP: If you already know JavaScript, check out TypeScript next, which is an enhanced version of JavsScript that provides static typing, classes, and interfaces. 

2. Python

Python has always been a popular programming language to learn as it’s incredibly beginner friendly. It isn’t verbose, and you’ll be able to build your coding skills quickly. In fact, we recently asked a selection of expert developers to share which programming language they recommended for a complete beginner and Python came out on top. It’s also a great language to learn due to the ever-growing demand for it in the job market. Whatsmore, Python will be even more relevant to learn this year as it’s also the most popular language for machine learning, which is becoming increasingly important.

3). Java

Every now and then, a lot of new programming languages get introduced. But even after 22 years, Java has not lost its popularity.
One of the reasons why Java is so popular is because it is platform independent. What that means is that it can run on almost any of device. Android applications also use Java.
According to Gooroo Worldwide's salary analysis, the average worldwide salary of Java developers is over $94,000 USD and over 19,000 jobs are advertised monthly

4. C#

Even though it was first released in 2000, C# has evolved at a steady pace and is still considered one of the most modern and popular programming languages used today. It’s easy to code and used in all types of software development. From writing web applications that run on most web servers, to mobile applications that run on practically any mobile device, and even in 3D games. In fact, C# will be a particularly valuable to learn this year as it’s used in Unity, which is the game engine that powers AR (Augmented Reality) and VR (Virtual Reality) experiences.
Another bonus to learning C# is that it can help prepare you to learn other languages. For example, C# and Java not only have similar syntax, they also share conceptual, architectural, and runtime similarities. So once you’ve grasped the fundamentals of C#, you ‘ll find yourself able to apply your understanding to other languages as well.

5). PHP

You might be wondering why PHP is even on this list !!
Let me give some interesting facts about PHP:
  1. It's very easy to learn and free to use (open source).
  2. PHP is installed on almost every web hosting server. So if you have created your website using PHP and want to make it available on the internet, you can choose just about any hosting provider and deploy your website on the server and it just works fine.
  3. Almost 30% of all the websites that exist on the internet are powered by WordPress. WordPress is a content management system (CMS) which is used to build and maintain simple and beautiful websites without having to know how to code. WordPress uses PHP as its programming language. So there are a lot of clients who have a WordPress website and, most of the time, they need to add a feature to their website. So there is a lot of opportunities to work for these clients by helping them enhance their WordPress website using PHP.
