What is a Variable?

A variable is like a box where we keep something. We give the box a name (a label), and we put a value inside it. Later, we can look inside the box, use the value, or change it to something else.

For example, think of a school bag. The bag stays the same, but what you put inside it can change. Today you might put books, tomorrow you might put lunch. The bag is like the variable, and whatever is inside it is like the value.

let studentName = "Abishek";

let studentAge = 21;
