Understanding Variables in JavaScript: A Complete Guide

Variables are one of the core elements of JavaScript programming. They allow you to store and work with data, which makes interactive and dynamic behavior possible in applications. Whether you are writing a small script or a full application, knowing how variables work is essential.

A variable is a named container that holds a value. That value can be used, changed, or referenced later in the program.

Example:

let age = 25; let name = "Sophie"; let isMember = true;
