How to make JavaScript

Learn how to make your JavaScript code more efficient with an example.

JavaScript Example

JavaScript is a high-level, interpreted programming language. It is a language that is used to control the behavior of web browsers and other applications. JavaScript enables interactive web pages and is an essential part of web applications.

The following example shows how to write a basic JavaScript program. It displays a message in the browser's console.

// This is a JavaScript program
console.log('Hello, world!');

The first line of this program is a comment, which starts with two forward slashes (//). Comments are ignored by the JavaScript interpreter and are only used to provide information to the reader. In this case, it is used to provide a brief description of what the program does.

The second line is an instruction to the interpreter. It tells the interpreter to display the message "Hello, world!" in the browser's console. The console is a special area in the browser where you can view messages written by JavaScript programs.

This example is a very basic program and doesn't take advantage of some of the more powerful features of JavaScript. However, it's a good starting point to learn the language.
