Choosing to learn the most widely used programming languages certainly has several advantages. One of them is that you don’t waste time on something that isn’t certain to be in high demand.

So what are the most used programming languages today, and maybe you need to learn them.

What is a Programming Language

According to Wikipedia, a programming language is a system of notation for writing computer programs. Or more clearly, a programming language is the basic commands to run functions on a computer.

Usually a programming language consists of two sets, namely syntax and semantics to define a program.

Most Used Programming Languages

1. JavaScript

Used For:

  • Web Development
  • Game Development
  • Desktop Software and Mobile Applications
  • Servers

According to a survey from Stack Overflow, JavaScript has been the most used programming language for many years, up to the present.

There is a reason why this programming language is the most widely used. This is because JavaScript works in the browser and is used on websites, it is clear that JavaScript is involved in almost every website in the world.

In addition, JavaScript is a language that is easy to learn but has complete features and is lightweight to run. Thus, this language has become popular among developers.

Over time, JavaScript can now be used in almost every program such as Websites, Games, Software or Applications to Servers.

2. HTML and CSS

Used For:

  • Web Development
  • Applications

In line with JavaScript, websites need HTML and CSS to display content and attractive designs for users. Thus, HTML and CSS have become one of the most widely used programming languages by developers.

Although HTML is a markup language, which cannot perform functions like other programming languages. However, HTML is still worth learning, especially for beginners.

Unlike CSS, although it is not a programming language, it can perform certain functions. In fact, advanced CSS can create interactive websites without JavaScript.

3. Python

Used For:

  • Data Analysis
  • Machine Learning
  • Web Development
  • Back-end Development
  • Software

Python is a programming language with a simpler syntax compared to other similar programming languages, such as Java or C. Therefore, Python has become popular and liked by developers.

However, it should be noted that Python is a slower programming language compared to C or Java.

4. SQL

Used For:

  • Modifying database tables and indexes
  • Adding, deleting, editing data
  • Accessing data in the database

SQL (Structured Query Language) is a programming language used to manage and perform many operations on relational databases. According to the same survey from Stack Overflow, SQL is ranked number 4 as the most used programming language.

5. TypeScript

Used For:

  • Front-end development
  • Back-end development

One of the most widely used programming languages is TypeScript. This programming language is a broader version of JavaScript, which was created with the aim of simplifying the development process.

TypeScript is a statically typed programming language, and is clearly different from JavaScript which is dynamically typed. In addition, the additional features in TypeScript that can speed up productivity, make developers like it.

Although, in the end, every line of code written in TypeScript will be compiled into JavaScript first before being executed.

6. Java

Used For:

  • Software Development
  • Game Development
  • Back-end Development

Java is a programming language that has been around for a long time and powers millions of applications every year. In addition, quality Java learning resources are scattered out there, making it easy for anyone to learn it.

One of the advantages of the Java programming language is that it is fast, secure and reliable. So it is not without reason for Java to be a widely used programming language today.

7. C Language

Used For:

  • Operating System
  • System Language
  • Software

The C programming language is one of the most widely used today. Although, this programming language has been around for a long time.

The ability of the C programming language is unquestionable, because the C language is a low-level programming language. This means that this language works similar to machine code, so its performance is very high.

8. PHP

Used For:

  • Web Development
  • Back-end

Another one of the most widely used programming languages is PHP. This programming language is used by the world’s largest CMS, namely Wordpress.

Interestingly, even though many have abandoned PHP and there are arguments that PHP will be abandoned. However, in reality, until now there are still many who are interested in PHP.

Other Programming Languages

If the list above feels incomplete, here is another list of programming languages that are widely used in 2023.

  1. C++
  2. C#
  3. Go
  4. Rust
  5. Kotlin
  6. Lua
  7. Ruby
  8. Dart
  9. Assembly

Final Words

After reading the most used programming languages today, we know that JavaScript is the most popular. However, that does not mean that other programming languages are not widely used.

Sometimes programming languages complement each other, and have their respective uses. So, what programming language is widely used and do you think is worth learning?
