Top 10 Programming Languages To Learn In 2020


If you want to stand out from the competition, then you must know more than one language. Expert in one language era is almost over. Technology is changing rapidly fast. Big companies are spending billions of dollars in Research and Development, and practically every year, they come up with the new technology and platform environment in which we need to work and learn.

Each programming language is good for something specific project but not so great for others, and it makes sense for Programmers and senior developers to know more than one language so that you can choose a right tool for a job. My first job was as PHP Developer, and I still like it and by far one of the most natural languages to work with. Now, let’s list Top 10 Programming Languages To Learn In 2020.

This list is based on the popularity of languages and my research and development. Your opinion may be different, and I am not here for debate. Your opinion is also welcome.

Top 10 Programming Languages 2020

  • Number 10: Swift (IOS Development)
  • Number 9: Kotlin (Android Development)
  • Number 8: C# (.net Development)
  • Number 7: R (AI and Machine Learning)
  • Number 6: PHP (Web Development)
  • Number 5: Golang (For building big distributed systems)
  • Number 4: C & C++ (Mainly used for building network and gaming tool)
  • Number 3: Java (Building big enterprise-level secure applications)
  • Number 2: Javascript (Frontend like React, Angular, Vue and backend like Node.js )
  • Number 1: Python (Almost for all-purpose especially in Machine Learning and Big Data)

10: Swift

If you are obsessed with iOS apps and want to become an iOS developer, then Swift is a must programming language. 

Swift has replaced the Objective-C as the primary language for Apple-related software and application.

Since it is supported and promoted by Apple Inc, so there is an increase in popularity since its inception.

As Apple is going to continue with it, so if someone is looking for an Apple-specific development platform like iOS, then Swift is going to be the must-know programming language for devs.

This is mostly vendor and product-specific language with minimal usage outside Apple’s eco-system.

Swift is deeply influenced by Python and Ruby and was designed to be beginner-friendly and fun to use.

Swift is considered to be the faster, more secure, and easier to read and debug than its predecessor Objective-C.

9: Kotlin

If you are thinking seriously about Android Application development, then Kotlin is the programming language to learn this year.

It is the next big thing happening in the Android world.

Kotlin is the new programming language from JetBrains, the maker of the world’s best IDEs.

Kotlin comes from industry, not academia and that is one huge advantage

It solves problems faced by working programmers today.

Kotlin has got native support, and many IDEs like IntelliJ IDEA and Android Studio are supporting Kotlin for Android development.

Kotlin compiles to JVM bytecode or JavaScript.

Kotlin programs can use all the existing Java frameworks and libraries. So, now it is the best time to learn Kotlin if you want to become an android developer.

8: C#

C-sharp is utilized in developing desktop applications and, more recently, Windows 8/10 applications and requires the .NET framework to function.

C# is a new language created by Microsoft and submitted to the ECMA for standardization. This new language was created by a team of people at Microsoft led by Anders Hejlsberg.

Interestingly, Hejlsberg is a Microsoft Distinguished Engineer who has created other products and languages, including Borland Turbo C++ and Borland Delphi.

With C#, they focused on taking what was right about existing languages and adding improvements to make something better.

Spotting errors in C# are easy as it is statically typed language, where the code is checked before turning it to the application.

In short, it is perfect for developing web applications, desktop applications, and also proved itself in VR, 2D, and 3D gaming.

Cross-platform tools like Xamarin have written in C# makes it all devices compatible.

7: R

If you want to become the data scientist, then you should learn the R language.

R is gaining popularity in recent years, and reason would be the growth and demand for data analysis.

R is used by data scientist but again much behind in comparison to Python, which has established as a general-purpose languages and enjoy active developers with lots of data science libraries and modules.

So, one can prefer the Python over R if they have to choose only one; otherwise, if wanted carrier in Data Sciences, then learning both will be a good option.

R provides the wide variety of statistical (linear and nonlinear modeling, classical statistical tests, time-series analysis, classification, clustering, …) and graphical techniques, and is highly extensible.

Whereas the S language is often the vehicle of choice for research in statistical methodology, and R provides an Open Source route to participation in that activity.

6: PHP

PHP is a serverside scripting language.

Over 60% of websites are built in PHP, and over 25% of the total website build on WordPress.

In Web development, PHP is still the most used language which has a variety of CMS and Frameworks.

Right now, PHP 7.3 is the latest version, and it has a great support community.

Laravel is the most used PHP web framework for building small, medium, and large enterprise applications.

Facebook, Dropbox, and many big tech websites are using PHP as a backend programming language.

PHP stands for Hypertext Preprocessor, is a general-purpose programming language.

PHP is the scripting language, which runs on a server, and it is used to create web pages written in the HTML.

It is popular because it is free, cheap, easy to set up, and simple to use for new programmers.

PHP is the compelling option for web developers around the globe.

It is widely used to create dynamic web page content and images used on websites.

It’s hitting on number #6 because of its broad range of usage.

Also, PHP is well dressed for the WordPress CMS (Content Management System).

In this blog, I have covered PHP Tutorials and Laravel Tutorials. Please do check it out.

5: Golang

The Golang was reportedly conceived by developers at Google when they were waiting for the code compilation to complete in the project.

This is precisely why Golang is the only language that incorporates all three sought-after capabilities, namely, ease of coding, efficient code-compilation, and efficient execution.

Bringing all these capabilities in one language is what made Golang so special.

Go or Golang, as it is called, is the powerful system-level language used for programming across large-scale network servers and big distributed systems.

Go is just like C/C++ comes as a compiled language, and this makes it as high-performing as them.

On the other hand, Go is also like Java for the allocation of variables, and it uses garbage collection and object removal. This makes Go as an ideal language to work within any hardware system.

In this blog, I have covered the basic Golang Tutorials. Please do check it out as well.

4: C & C++

Both C and C++ are evergreen languages, and many of you probably know them from school.

C++ is a programming language, which has essential and object-oriented features. It is also referred to as a middle-level programming language. Bjarne Stroustrup develops it at Bell Labs since 1979.

It has first appeared in the year 1985.

But if you are doing some serious work in C++, I can guarantee you that your academic experience will not be enough.

C has been the parent language of the handful other langauges; some are either derived from C or inspired by its syntax, constructs, and paradigms, including Java and C#.

Even nowadays, it is seen, whenever there is a need to build high-performance applications, C remains the most popular choice.

Linux OS is C based. And CPP is the hybrid version of C.

C++ is the object-oriented programming language and which is built on C; therefore, it is preferred over others for designing higher-level applications.

C++ sees as more performing than dynamically typed languages because the code is type-checked before it is executed on real grounds.

Core areas of development are Virtual Reality(VR), gaming, computer graphics, etc.

In this blog, we have also covered the C++ Tutorials. Feel free to check it out.

3: Java

If anybody asks why java, most frequent sentence comes up would be “write once, run everywhere”: Java has been the ruling programming language for the last 20 years.

Java is 99% object-oriented and is powerful as java objects contain no references to data external to themselves. It is simpler than C++ because Java uses automatic memory allocation and garbage collection.

Java is highly cross-platform compatible or platform-independent.

Since you can code anywhere (I mean on all devices), compile into low-level machine code, and finally, execute on any platform using JVM – Java Virtual Machine (which is platform dependent).

Java formed the base for the Android operating system and opted around 90% fortune 500 companies for making a variety of back-end applications.

I would not hesitate to take the biggest sensation Apache Hadoop data processing, run by Amazon Web Services(AWS) and Windows Azure.

With so many good reasons and a wide range of business applications, possessing immense flexibility and java is all the time beginners’ favorite.

If you want to learn basic Java, then we have covered for you. Check out these Java Tutorials.

2: JavaScript

There is a saying by Stackoverflow cofounder: If any application can be written in Javascript should be written in Javascript.

In the last 6-7 years, Javascript has changed the Web and Mobile world completely by introducing ES2015 standard.

10 years ago, Javascript only called Client-side scripting language, but now it is used for Full Stack development because of Node.js introduced by Ryan Dahl.

For backend development, you can use Node.js as a platform and Javascript as a language.

For frontend development, there are lots of choices available. I will list the main three.

  1. Angular
  2. React
  3. Vue

For mobile development, React Native is widely used.

If you are using React Native, then you need to write one codebase, and it will compile and run in Android and iOS devices.

If you want to build a desktop application like Visual Studio Code, then you can use the Node.js’s Electron framework.

No matter what backend you are using, there is always a requirement for a Frontend developer.

That is why Javascript is must known programming language to the developer. At least basics would work fine, but if you want to build a career in that, then you need to learn deep enough to stand out from the competition.

There is tremendous community support out there who can help you to write better Javascript applications.

1: Python

In 2020, the Number 1 programming language will be Python for many reasons.

Right now, all the industries are transforming into AI and data-driven, and Python is the language that has all kinds of different mathematical and algorithmic packages available.

If you are watching tech news, then now and then, you will see that big tech companies are making considerable investments in AI and Machine Learning.

In Github, there are over 1 million packages available to work with, and you can build almost anything using Python programming language.

Python has enormous community support, and developers are making tons of third party open source packages so that you do not need to reinvent the wheel.

Python is mostly used for the IoT cloud applications, respectively, in the IoT Developers survey 2019. This language is compatible with IoT for several reasons, such as a vast developer community, a large number of libraries, tools, and much more.

Python is a compelling language and excellent to generate scripts. You will find a python module for everything you can think of.


These are my top 10 programming languages to learn in 2020 list.

If you search this topic on the internet, then you can find a different list, and that is fine. Everyone has their opinion and research.

The point here is that you need to upgrade your skill every year to stay in the competition; otherwise, you need to do struggle to find a better job.
