Imagine playing a video game where every time you collect a coin, the game instantly forgets how many you have.
To track high scores, player names, and remaining health, computers need a dedicated place in memory to hold onto information while a program runs.

What Is a Variable?

A variable is a named storage container in computer memory that holds one piece of data at a time.
Think of it like a labeled box: the label tells you what belongs inside, and the value inside can be looked at or changed whenever your program needs.
What different types of information can we actually store inside these memory boxes?

Storing Different Kinds of Data

Variables can hold numbers, written words called a string (wrapped in quotation marks), or simple true-or-false flags called a Boolean.
If a game uses dozens of variables at the same time, how do we keep them from getting hopelessly mixed up?

Labeling Variables Clearly

A good variable label is descriptive, meaning anyone reading your code instantly understands exactly what information is stored inside.
