The most used programming language often varies depending on the metric used to measure it. However, JavaScript is commonly listed as one of the most used and popular programming languages.

Here is a simple example of a program written in JavaScript:

console.log("Hello, World!");

This script will output the text "Hello, World!" to the console when run.

It's important to note that other programming languages such as Python, Java, and C are also widely used.

According to various sources such as GitHub's Octoverse and TIOBE's index, JavaScript is currently the most widely used programming language. It is a high-level, interpreted language that is commonly used for front-end web development, but it is also used for server-side development and for building mobile and desktop applications.

Here is an example of a simple "Hello, World!" program written in JavaScript:

console.log("Hello, World!");

This program can be run in a browser's developer console, or in a Node.js environment by saving the code to a file with a .js extension and then running the file with the node command.

Other popular programming languages include Python, Java, C#, and C++.

The most used programming language varies depending on the source, but Python is often cited as the most popular in terms of overall usage and growth. For instance, Python tops the TIOBE Index in March 2025 with a significant rating increase[3]. Here's a simple example of Python:

print("Hello, World!")

This is a basic "Hello, World!" program that prints the message to the screen, demonstrating the simplicity and readability of Python.
