Programming Languages ​​You Should Learn in 2020

Programming languages ​​and computer coding have made life simpler for us. Whether it’s a car, bank, household appliance, or hospital, every aspect of our life depends on a code. Unsurprisingly, coding is one of the core skills required by most of today’s high-paying jobs. Coding skills are invaluable in the IT, data analytics, research, web design and engineering segments. 

So, which programming languages ​​will continue to be in demand in 2020 and beyond? How many languages ​​do you need to know to pursue your dream career? We will try to answer this tricky question in this post. 

The ever-growing list of programming languages ​​and protocols can make it difficult for programmers and developers to choose the one language best suited for their job or project. Ideally, every programmer should have knowledge of languages ​​that are close to the system (C, Go, or C ++), object-oriented languages ​​(Java or Python), functional programming languages ​​(Scala), and strong scripting languages ​​(Python and JavaScript). ). 

Whether you intend to join a Fortune 500 firm or want to pursue a work from home career in programming, it’s important to know what’s trending in the industry. Here are some of the programming languages ​​we recommend for coders looking to succeed in 2020. 

1. Python

Python continues to be one of the best modern programming languages ​​every developer should learn this year. The language is easy to learn and offers clean and well-structured code, making it robust enough to build decent web applications. 

Python can be used for web and desktop applications, GUI-based desktop applications, machine learning, data science, and network servers. The programming language enjoys enormous community support and offers several libraries, frameworks, and open source modules that make application development easy.

For example, Python offers Django and Flask, popular libraries for web development and TensorFlow, Keras, and SciPy for data science applications. 

Even though Python has been around for quite a while, it makes sense to learn the language in 2020 as it can help you land a freelance job or project quickly, thus accelerating your career growth. 

2. Kotlin

Kotlin is a general purpose programming language with type inference. It is designed to be fully interoperable with Java. Plus, ever since Android announced it as its first language, Kotlin offers the features developers are asking for. It easily combines object-oriented and functional programming features in it.

Easy interoperation between Java and Kotlin makes Android development faster and more enjoyable. Because Kotlin addresses a major problem that arose in Java, some Java applications are rewritten in Kotlin. For example, brands like Coursera and Pinterest have moved to Kotlin due to strong tool support.  

As most businesses move to Kotlin, Google is bound to promote this language over Java. Hence, Kotlin has a strong future in the Android app development ecosystem.

Kotlin is an easy to learn, open source, fast language for Android app development that removes all barriers to adoption. You can use it for Android development, web development, desktop development, and server side development. Hence, it is a language that Android programmers and app developers should learn in 2020. 

3. Java

Java celebrates its 24th anniversary this year and has become one of the most popular programming languages ​​used for developing server-side applications. Java is a practical choice for developing Android applications because it can be used to create highly functional programs and platforms. 

This object-oriented programming language does not require a specific hardware infrastructure, is easy to manage, and has a good level of security. In addition, it is easier to learn Java compared to languages ​​like C and C ++. Not surprisingly, nearly 90 percent of Fortune 500 companies rely on Java for their desktop applications and backend development projects. 

Despite the age of the industry, Java is very stable and won’t be retiring any time soon. This makes Java one of the most desirable languages ​​among programmers in 2020. 

4. JavaScript / NodeJS

JavaScript (also known as NodeJS) is a popular language among developers who need to work on both server-side and client-side programming. It is compatible with several other programming languages, allowing you to create animations, arrange buttons, and manage multimedia. 

Due to its high speed and regular annual updates, JavaScript is the last hit in the IT domain. Well-known companies like Netflix, Uber, PayPal, and several startups use JavaScript to create fast and secure dynamic web pages. In fact, the 2018 Developer Skills Report by HackerRank shares that JavaScript is the top programming skill companies need today. 

JavaScript is ubiquitous in today’s digital environment. Hence, learning this language made a lot of sense. 

5. TypeScript

TypeScript, a superset of JavaScript is an object-oriented language that was introduced to extend the capabilities of JS. This language makes it easy for developers to write and maintain code. TypeScript offers a complete description of each code component and can be used to develop large applications with a strict syntax and fewer errors. 

Furthermore, it is well structured and easy to learn. Its expanded toolbox makes app development fast. Because of the benefits it offers, TypeScript is expected to replace JS in 2020, making it one of the most sought-after programming languages ​​of the future. 

6. Go

Go is a new system level programming language that has a focused vocabulary and simple scoping rules. It combines the best aspects of functional programming and an object-oriented style. Go is the fastest growing language on Github, intended to replace languages ​​like Java and C ++. 

The Stack Overflow survey revealed that Go is the fifth most preferred language among developers today. This is because, Go solves problems like slow compilation and execution in large distributed software systems. 

This speed advantage makes Go an essential component of the cloud infrastructure. So, if you plan to work in a serverless ecosystem, Go is the language for you. 

7. Fast

Swift is a general-purpose compilation programming language developed by Apple that offers developers a simple and cohesive syntax. It is heavily influenced by Python and Ruby which are fast, safe, and easy to learn. Due to its versatility and practical application, Swift has replaced Objective-C as the primary language for Apple-related applications. 

Furthermore, since Swift was promoted by Apple, its popularity and community support has increased. In fact, a study of the top 110 apps in the app store shows that 42 percent of apps are already using Swift. 

Coders with little or no experience can use Swift Playgrounds to learn languages, experiment with complex code, and work on native iOS and macOS apps. Swift is the premiere coding language that helps developers build iOS apps in no time. Programming languages ​​open up several opportunities for new programmers, enabling them to make it big in the world of application development. 

There’s a huge market out there for iOS and you’ll want to be a part of it. If you are eyeing this growing market, Swift is the language you should learn in 2020. 


Almost all coders are hungry to learn a new language. However, knowing which languages ​​are gaining popularity and can ensure better career growth will help you prioritize learning them first. Use the information shared in this post to make the right decision in this matter.
