A named box that stores a value in a program.
Start with the idea
A variable is a name given to a place in memory where a program keeps a value. The value can change while the program runs.
For example, a game might have a variable called score. It starts at 0 and goes up every time you collect a coin.
Variables can hold different kinds of data, such as numbers, text or true/false values.
