Top 5 Programming Languages in 2021

As of 2020, there are about 700 programming languages available. Some of these tend to be applied just for specific domains while others are widely appreciated for their ability to be able to work in a wide range of applications. During the past decade, there has been an almost steady growth in the application of software and new languages have been developed in order to meet the demand.

According to the 2020 Stackoverflow Developer Survey, the following programming languages were the ones most loved by developers in 2020

Additionally, according to the Stackoverflow Developer Survey, these were the top 10 paying programming languages in 2020

Python

It was first developed in 1991 by Guido van Rossum and since then it has just been increasing in its popularity.

Most often, Python is used in Data Science, Machine Learning, Web Development, Computer Science Education, Computer Vision, and Image Processing, Game Development.

Besides, it is considered one of the easiest software languages to learn and master. Also, Python is undoubtedly the best starting language for beginners. Often named one of the world’s most popular programming languages, Python powers the backend stacks of many startups and is essential in the growing fields of data science and AI

Python has surpassed javascript in the past 5 years. Besides, it has a very wide range of applications like Web & Desktop Development, Network Servers, Machine Learning, GUI Based Desktop applications, In Enterprise and Business and Data Science, etc

Go

Go is nowadays one of the most promising system programming language. This programming language was in fact developed by Google in order to make application and development scaling easier. Some of the key characteristics of Go are:

  • Designed for Cloud-Native Development. In fact, mainstream tools such as Docker and Kubernetes have been developed using Go.
  • Memory Management (unlike languages such as C and C++ has an embedded Garbage Collector).
  • Excellent Concurrency support.

After reaching a peak around 2014, Go had a quite consistent amount of Google searches throughout the years. Go is currently one of the most popular programming languages on Cloud platforms such as Google Cloud Platform and Microsoft Azure.

Kotlin

Kotlin was developed by the Jet Brains team in an attempt to find “something better than Java.” Many experts claim that the goal has been achieved. Like Go, Kotlin cannot be called the trendiest programming language. But statistics show that demand is growing.

The effortless interoperation between Java and Kotlin makes Android development faster and enjoyable. Since Kotlin addresses the major issues surfaced in Java, developers have rewritten several Java apps in Kotlin.

According to the Hired ratingKotlin is one of the five most popular programming languages in the world. It beat competitors such as Java and Python, giving in only to Go and Scala in its field.

Javascript

Javascript is currently one of the most popular web programming languages and can run for almost any type of application (e.g. server, mobile, cloud, micro-controllers, etc…).

Javascript reached it’s a peak in popularity during the early days of web-development and since then has had a quite steady trend during the last decade

It is widely known for adding interactive elements to web applications and browsers. Most front-end developers prefer JS. However, the Node.js runtime provides significantly more features than just front-end development

JavaScript is the most popular language, according to a Stackoverflow survey. The same survey showed that 66% of respondents like to work with JS. 17.8% of respondents want to master JS

Java

Java is one of the most common, in-demand computer programming languages used today. 

Owned by Oracle Corporation, this general-purpose programming language with its object-oriented structure has become a standard for applications that can be used regardless of platform (e.g., Mac, Windows, Android, iOS, etc.) because of its Write Once, Run Anywhere (WORA) capabilities. As a result, Java is recognized for its portability across platforms, from mainframe data centers to smartphones. Today there are more than 3 billion devices running applications built with Java.

Java is widely used in web and application development as well as big data. Java is also used on the backend of several popular websites, including Google, Amazon, Twitter, and YouTube. It is also extensively used in hundreds of applications. New Java frameworks like Spring, Struts, and Hibernate are also very popular. With millions of Java developers worldwide, there are hundreds of ways to learn Java. Also, Java programmers have an extensive online community and support each other to solve problems.

Java is a more complex language to learn, but experienced developers with Java coding skills are in high-demand. The average Java developer earns around $79,000 each year.

Typescript

Typescript is a well-known name. Since its release in 2014, it is growing rapidly and maintaining its place in the list of top 10 striking programming languages 2021.

It is developed by Microsoft. Well, it has emerged in response to growing dissatisfaction with JavaScript. Soon after its arrival, It impressed the Google team so much that they began working on developing TypeScript, instead of developing a new language.

Basically, TypeScript was used as the main programming language for the Angular2 + SPA structure. Even, Vue.js team is also using typescript as they announced in 2018 to develop new versions of its framework.

The reason behind its popularity is, it is easy for developers to write and maintain codes. Furthermore, it offers a complete description of each component of the code and can be used for developing large applications with a strict syntax and fewer errors

Scala

Scala is currently considered to be one of the best programming languages for functional programming (it does although still provide support for object-oriented programming approaches). In terms of search popularity, Scala seems to have peaked around 2018–2019 on Google Searches

Some of the key advantages of using Scala are:

  • Scala is a statically typed language.
  • Much faster compared to programming languages such as Python.
  • Compatibility with Java.
  • Ability to combine both functional and object-oriented programming.

One of the main reason for the popularity of Scala is Apache Spark (a data-management tool built with Scala). Apache Spark is in fact one of the most popular big data tools for Hadoop integration (fast processing of large amounts of data).

Rust

Rust is a multi-paradigm programming language designed for performance and safety, especially safe concurrency. While Rust is syntactically similar to C++, one thing that it can guarantee is memory safety by using a borrow checker to validate references.

As per the survey, Rust has been Stack Overflow’s most loved language for consecutive four years. Impressive, isn’t it? This huge popularity shows that those who have had the opportunity to use Rust have fallen in love with it.

Besides, Rust allows you to store data on the stack or on the heap and determines at compile time when memory is no longer needed and can be cleaned up. This allows efficient usage of memory as well as more

Swift

Swift is a general-purpose compiled programming language developed by Apple. It offers developers a simple and cohesive syntax. It is deeply influenced by Python and Ruby that’s fast, secure, and easy-to-learn. Owning to its versatility and practical applications, Swift has replaced Objective-C as the main language for Apple-related applications. 

Further, since Swift is promoted by Apple, its popularity and community support are increasing. In fact, a study of the top 110 apps on the app store showed that 42% of apps are already using Swift. 

Coders with little or zero experience can use Swift Playgrounds to learn the language, experiment with complex codes, and work on native iOS and macOS apps. Swift is the premiere coding language to create iOS apps within a short time. It opens several opportunities for new programmers, allowing them to make it big in the world of app development. 

There is a giant market out there for iOS and you definitely want to be a part of it. If you are eyeing this burgeoning market, Swift is the language you should learn in 2020-2021. 

R Programming

R programming language is most wanted when it comes to the data science arena. Supported by the R Foundation, it has been most used for creating statistical software and data analytical solutions. Libraries in R are apt to create detailed analysis with insightful designs and data visualization.

Since R is interoperable, it can handle many packages together and hence effectively deal with the databases. It is also utilized to create web applications. It can be used for distributed computing and does not need a compiler since it is an interpreted language.

R is used in machine learning solutions and innovative technologies. Users can prepare reports of their own choice and format, with R. It works well with Linux, Microsoft Windows, and GNU. Though it is a little tough to learn, it does offer appropriate techniques and coding styles for statistical analysis.

Key Features:
  • Free, open-source, and includes statistical analysis language
  • Holds a strong package ecosystem
  • Competency to execute seamlessly on various platforms
  • Increasing community support
  • Ability to make tweaks as per requirements

All programming languages are good and well-deserved, it depends upon the requirements and infrastructure on which one to choose. There are many languages which are used sparingly and a few widely. A lot of factors determine it’s usage.

 

Note: We have prepared this list after researching and observing the performance, demand, and usability of each in 2020, although, this data may change as data can’t be static. Knowing which languages are gaining popularity ensures a better career growth & help you prioritize learning them first
