Top Ten Programming Languages to Learn in 2021

We always find ourselves confused about which programming language is in demand in the coding industry! If we are a beginner in the coding journey we often find ourselves in the dilemma of which language we should learn first! 

Well, you don’t have to worry very much! We have compiled the list of top programming languages based on industry trends and the popularity of the programming language. This post guides you with a brief introduction of the Top 10 programming languages to learn in 2021:

1. Javascript

According to StackOverflow’s 2020 developer survey Javascript is the most commonly-used language in the world. Along with HTML/CSS, python and Java. Javascript is used to manage web pages. What you can do with javascript? 

1. 1. Create dynamic web elements – Animated graphics, Interactive maps, forms, buttons and more.
   2. Create and control the website user experience in terms of navigation and readability.
   3. Game development
   4. Mobile apps
   5. Build web servers

Javascript requires almost no prior coding knowledge. Once you start learning Javascript you can code and start playing with it immediately. It only requires continuous efforts to keep learning. Moreover, Javascript is ubiquitous, there are countless communities courses and avenues of support available online.

 2. Python

Python is a general-purpose scripting language that helps developers to use different programming styles such as functional, object-oriented, reflective etc and create applications and programs.  Several popular internet services like Google search, Youtube, Uber etc uses python to develop digital tools and platforms. Python has a very simple syntax and easy to remember English like keywords. As this is an “easy-to-learn” and “easy-to-use” programming language. This is ideal for beginners and for someone who wants to get into the software domain. Python has an extensive list of libraries that support commands and tasks. It is interactive and one can test the code on the go, this helps in reducing the time spent in debugging and testing long sections of code.

What can you do with python?

1. Build and deploy backend API for websites.
2. Create and experiment with machine learning, deep learning and artificial intelligence algorithms.
3. Develop different types of desktop and android applications and software.

3. Swift

Swift is the programming language for you; if you are interested in app development for Apple products. Swift has been optimized and built from the ground up to match the realities of iOS development. It was announced by Apple in 2014 and is the new programming language used to develop iOS and macOS application.

This is also the basis for operating systems such as watchOS used in Apple watches and tvOS used in Apple TVs. This is a very specific programming language for Apple operating systems and Apple products learning Swift can help you create or port applications to Apple devices.

4. Java

Java is a general-purpose and object-oriented programming language. With this, you can create objects that encompass methods and data which can later be used to program complex applications and software. Java is at #5 on Stack Overflow’s list of most commonly used languages in the last two years. This is one of the most sought programming languages for hiring managers globally. Java is relatively easy to learn and use language. It has incredible security and can handle massive amounts of data. Being a platform-independent programming language this supports a wide range of setups and hardware. With a help of a small JDK, you can run java programs on almost every device, that’s everyone quotes Java as a “code once, run anywhere” language.

What can you do with Java?

1. Build complex e-commerce websites.
2. Build complex finance applications
3. App development.

5. GO

Go is developed by Google in 2007. It is a top-tier programming language. Go stands out for its efficiency and concurrency. Which means you can execute multiple processes concurrently. Go has the support of extensive “vocabulary” which means it displays more information than any other programming language. It has syntax similar to C but it provides a high level of memory management and safety features. Go is not only the most-loved by programmers but it is also most-wanted in industry. 

What can you do with GO?

1. Build System/network programs
2. Build efficient tools for audio/video editing
3. Manipulate and use Big Data
4. Create and deploy efficient web apps.

6. Scala

As a functional programming language, Scala allows you to increase the quality of your code and resemble pure math. If you are familiar with Java – it’s worth checking its cousin, Scala. This combines the best features of Java such as object-oriented structures and a super-fast JVM runtime environment with a modern twist. Scala supports concurrent programming with which one can execute complex procedures in parallel.

7. SQL

Structured query language is a language that allows you to query and manipulate databases. It is designed for maintaining data in a relational database management system (RDBMS). In simple words, this can create records in the database, locate and retrieve data from the stored database. As SQL is highly functional, it tends to work better with small databases and doesn’t always tend to manage expensive one’s. 

8. Ruby

Ruby is a scripting language that is commonly used for web development. It is used as the basis for the Ruby on Rails web application framework. Learners are often attracted to Ruby as it has one of the friendliest and most helpful communities. In addition to the active community, this has a simple straightforward syntax. Twitter, Airbnb, Bloomberg Shopify and many other startups have built their websites using Ruby on Rails.

9. C#

C sharp belongs to the object-oriented family of programming languages. This was released by Microsoft back in 2002 and today it stands as a much-loved improvement on C++. As a general-purpose language, C# is gaining popularity for developing web and desktop applications. According to Hackerrank at least one of every five hiring manager is looking for a C# developer. There is a big community that works with C# and offers support to newbies. C# is ideal for building ever-more-popular mobile apps and games.

10. Rust

According to Stack Overflow, Rust has consistently ranked at the top of the most-loved programming language. With more than 86% of users claiming that they were interested in developing applications with it. However, Rust users only account for 3% of the total developers in the survey. Rust is a “Multi-paradigm” programming language.

This means that it allows developers to work in a variety of programming styles. Coming to syntax it is comparable to C++, though it supports wide-ranging applications. If you are looking for faster compilation, better cross-platform capabilities then Rust is the best choice for you.
