But first, let’s go over how we came up with this list in the first place. We had two key research questions when we sat down to figure out what the most popular programming languages may be: Which languages are now in demand? Which is becoming increasingly popular and will be in high demand in the near future? You may probably imagine why we asked the first question. While following trends isn’t always the greatest approach to determining which languages to prioritize, the popularity of a language might suggest its market prominence. Here’s a basic rule of thumb: the more popular or widely used a language is, the more probable it is that a developer will have to deal with it. will need to deal with it at work.

Following that, we analyzed which abilities are likely to become the most in-demand programming languages on the market. To do so, we combed through Stack Overflow’s developer polls over the previous two years, focusing on:

The languages that developers report using and intend to employ in the future
The languages that developers are interested in but have not yet used.

We hoped to acquire a better picture of which languages will become popular in the coming years by examining these tendencies.

Now that we’ve covered our procedure, let’s get to the point: what are the most in-demand coding languages?

The Most In-Demand Programming Languages

1. JavaScript

What this language is used for:

• Web development
• Game development
• Mobile apps
• Building web servers

According to the 2020 Developer Survey from Stack Overflow, JavaScript is the most commonly used language in the world (69.7%), followed by HTML/CSS (62.4%), SQL (56.9%), Python (41.6%), and Java (38.4%). It is also the programming language most sought after by recruiting managers in the Americas.
JavaScript is used to control how web pages behave. Coders can use it to construct dynamic web features including animated images, interactive maps, clickable buttons, and more. HTML, CSS, and JavaScript programmers get greater website control and can deliver a better user experience in terms of navigation and readability.

2. Python

What this language is used for:

• Back end development
• Data Science
• App development

Python is a general-purpose programming language that allows developers to create programs in a variety of programming styles (for example, functional, object-oriented, reflective, and so on). Python has been used to create a number of popular digital tools and platforms, including YouTube, Google Search, and iRobot machines. It is also the second-most in-demand programming language for recruiting managers in the Americas, according to HackerRank.
Python is suitable for both beginners and expert coders because it is one of the easiest languages to learn and use. The language includes a large library that covers common commands and actions. Its interactive features enable programmers to test code as they go, decreasing the amount of effort spent generating and testing lengthy chunks of code.

3. HTML

What this language is used for:

• Web documents
• Website development
• Website maintenance

HTML is an abbreviation for HyperText Markup Language. Don’t be fooled by the sophisticated name; HTML is one of the most straightforward entry points into the world of programming.
HTML is a markup language, which means it is in charge of styling the display of content on a webpage. HTML is mostly used to define web pages with plain text. It lacks the capability of the other programming languages on this list and is restricted to writing and arranging text on a website. HTML domains include sections, headings, links, and paragraphs.

4. CSS

What this language is used for:

• Web documents
• Website development
• Website design

CSS, or cascading style sheets, is commonly used in conjunction with HTML and regulates the design of the site. While HTML is responsible for organizing site text into chunks, CSS is in charge of deciding the size, color, and location of all page elements.
CSS is also convenient; the cascading portion of the name refers to how an applied style cascades down from parent elements to all children elements across the site. This feature eliminates the need for users to manually replicate their code across a website once they’ve determined the aesthetics for the main parent. Furthermore, by delegating site organization to HTML and aesthetics to CSS, users do not need to totally recreate a web page only to alter the color.

5. Java

What this language is used for:

• E-commerce
• Finance
• App development

Java is an object-oriented programming language that is widely used. Object-oriented programming allows developers to build objects that have functions and data and can subsequently be used to structure programs and applications.
Java is now the third-most sought-after programming language for hiring managers worldwide, and it has ranked fifth on Stack Overflow’s list of the most regularly used languages for the past two years. Java’s success is well-deserved; the language is simple to learn and use, has excellent security, and can manage large amounts of data. These characteristics make Java a perfect language for online finance, and it is frequently used in areas such as banking, billing, and the stock market.

6. SQL

What this language is used for:

• Database management
• Sales reports
• Business management

SQL, or Structured Query Language, is a programming language used to query and manage databases. As a domain-specific language, it is primarily intended for data administration within an RDBMS (relational database management system). Simply put, SQL can find and retrieve data from a database, as well as edit, add, and delete records.
While SQL is extremely practical, it works best with small databases and does not always lend itself to managing large ones.

7. NoSQL

What this language is used for:

• Database management
• Sales reports
• Business management

NoSQL, or Non-relational SQL, was developed to improve SQL’s scalability while preserving the ease of use of the other language.
Remember that SQL employs relational database/stream management systems, which store data in tables and allow users to change and extract data. NoSQL databases, on the other hand, do not employ tables and can be more beneficial for specialized applications, such as storing data in a hierarchical network or enabling large-scale, cloud-based applications, than their predecessors.

8. C#

What this language is used for:

• Game development
• Desktop/web/mobile apps
• VR

This language, sometimes known as C Sharp, is part of the object-oriented programming language family. C# was introduced by Microsoft in 2002 and has since become a popular enhancement to the C++ coding language.
C# is gaining prominence as a general-purpose language for constructing web and desktop apps; according to HackerRank, about one out of every five hiring managers is seeking for a developer who can code in C#. There’s no denying that it’s one of the most in-demand coding languages for the coming year, but there are other reasons to keep it on your radar.

C#, like other popular languages, has a large community that works with it and helps newcomers.

9. Rust

What this language is used for:

• Operating systems
• VR
• Web browsers

According to Stack Overflow, Rust has continuously scored at the top of the most-loved programming languages, with 86% of users reporting an interest in continuing to develop with it.
However, Rust users accounted for only 3% of developers in the poll, indicating that the great majority of programmers are unaware of its use. Rust is a “multi-paradigm” programming language, which implies it allows developers to work in a number of programming approaches. Its syntax is similar to C++, but it offers a broader range of applications.

10. Perl

What this language is used for:

• System Administration
• GUI development
• Network programming

Perl is not the most widely used programming language on the market. In reality, only 3.1 percent of developers used it in 2020, and it didn’t even top Stack Overflow’s list of the most commonly used languages in 2019. We do, however, recommend it for a reason. If you’re already established in your field, learning Perl could greatly increase your income potential.
According to HackerRank, Perl developers earn 54 percent more than the average developer. However, it is worth mentioning that the majority of those who know these are senior engineers, who tend to make more at a base level attempting to quantify the “bonus” that a programming language delivers may be difficult.

11. Go

What this language is used for:

• System/network programming
• Audio/video editing
• Big Data

Go is a top-tier programming language that was created by Google in 2007. What actually sets Go apart is its efficiency; it can run multiple processes at the same time. And, in terms of computer languages, it has a large “vocabulary,” which means it can display more information than other languages.
Despite having a similar syntax to C, Go is a standout language that offers superior memory safety and management features. Furthermore, the structural typing capabilities of the language allow for a considerable lot of utility and dynamism. Furthermore, Go is not only high on programmers’ favorite and most-wanted lists; it also correlates to a 33% income increase.

Final Thoughts

Learning a new language is one of the finest ways to develop your programming career, whether you are an experienced coder or just starting out. But where do you begin your educational journey?
