And since Android is the most popular mobile platform, many businesses today need expertise from Android developers. Thanks to Google’s excellent Java-based Android development framework, Android Studio, Java developers can take advantage of a massive amount of opportunities. 

Java is not that easy to learn, but the job opportunities it brings are considerable enough to be worth the effort.

3. JavaScript

JavaScript is the most popular frontend programming language today. Developers use it to design interactive frontend applications for both web and mobile applications. Many businesses – and in particular startups – use NodeJS, a JavaScript-based runtime environment that allows using JavaScript for server-side scripting. 

Thanks to technologies like NodeJS, developers can run scripts server-side to build dynamic web page content before the page is sent to the web browser. With JavaScript, they can develop outstanding frontend but also use it for server-side programming. 

JavaScript is a perfect choice for those looking to move into frontend development and then potentially expand their capabilities to the backend thanks to NodeJS. Also, since it’s the most popular technology out there, you will find plenty of job opportunities in both large organizations and startups. Bonus points? JavaScript is relatively easy to learn, and beginners can take advantage of many resources available free of charge.

4. C/C++

Just like Java, C/C++ are battle-tested programming languages. The vast majority of low-level systems are written in C/C++ (for example, filesystems or operating systems). 

That’s why to become a system-level programmer, C/C++ is essential. However, the languages are also widely used by other developers because they’re fast and stable. 

C++ provides developers with a Standard Template Library (STL), a pool of ready to use libraries for various arithmetic operations, algorithms, and data structures. That’s why the programming language is such a popular choice for applications in the high-frequency trading niche. C/C++ is not that easy to learn, but it offers developers some really interesting job prospects.

5. Go

Go is short for Golang, a programming language built by Google. This statically typed language offers clear, clean syntax and a comprehensive standard library that includes many practical inbuilt functions. It also provides support for multithreading. 

That’s why so many companies that rely heavily on distributed systems need Golang experts. Many of them are hot startups located in Silicon Valley and beyond. Golang is perfect for building Single Page Applications and offers developers well-written documentation that makes the learning process easier.

6. Swift

Swift is a language for you if you’d like to enter the mobile scene, and iOS is your preferred operating system. Swift is a programming language development teams use to build applications for devices running on iOS like iPads and iPhones. 

Since iOS devices are becoming increasingly popular and gaining a significant market share, programming beginners who would like to become part of this niche need to gain some solid Swift skills. 

The language is quite easy to learn, and the job opportunities it brings are massive. Because of its structure, Swift encourages developers to write readable and clean code. Moreover, it allows integrating server-side Swift with any technology of your choice, so it’s versatile.

The best programming frameworks to learn in 2020

Now that you know which programming languages are most widely-used this year, let’s take a look at the most popular frameworks that help development teams build amazing web and mobile applications today.

1. Django

Django is a key framework in the Python ecosystem of tools that allow developers to build high-quality web applications. Teams use Django to quickly develop APIs and web apps. As an open-source framework, Django now counts several thousand projects. 

Moreover, Django is one of the best-developed web frameworks in the ecosystem. Many developers choose because of its innovative approach to problem-solving and the constant improvements added by the open-source community. 

Since Django is based on the Python programming language, it’s also easy to learn. Versatile and fast, Django is a perfect technology for those looking to gain a foothold in web development.

2. Spring

Spring is the most widespread application development framework for the Java programming language. In its essence, Spring allows developers to write backend web applications in Java. 

Developers use the Spring framework to create high-performing apps quickly and efficiently. If you’re a beginner in Java, learning Spring shouldn’t be a problem. And it’s worth investing your time into exploring Spring since it will become an essential part of your competencies as a Java developer.

3. ReactJS

ReactJS is actually not a framework, but a frontend JavaScript library. However, it fits into the list of frameworks because many developers consider it as one. ReactJS is very much in demand thanks to its component-based architecture that allows teams to accelerate and streamline the development process. 

By providing a straightforward and understandable interface, ReactJS enables developers to create any application they want. Another reason behind its popularity is the fact that ReactJS is used by Facebook to power both Facebook and Instagram platforms.

4. AngularJS

Another critical technology for web developers is AngularJS. Many web apps are created using AngularJS today because it’s based on another popular technology, JavaScript. It was developed and is currently maintained by Google, so we’re only going to see it to grow and expand as more and more tech giants decide to invest in it. 

AngularJS helps developers to build powerful web applications – in particular, ones that need to provide high performance and are large. The undeniable perk of AngularJS is that the applications built with it are easy to maintain. 

5. VueJS

Another JavaScript framework that will become big this year is VueJS, which offers developers some really amazing features. VueJS is a progressive framework. This means that if you already have a running project, you can still use VueJS on one part of it. And you can be sure that everything else will work just fine, without any problems, bugs, or errors. 

The straightforward architecture of VueJS means that solving issues is very easy. The framework isn’t backed by any tech giants, but its popularity is on the rise, so consider adding VueJS to your learning path.

6. Ruby on Rails

Rails is a Ruby-based framework that is best described as a Model-View-Controller framework. Loved by many developers, Rails is used by some of the greatest tech giants out there, such as Airbnb, Shopify, and Twitter.
