All about Variables in Coding
A variable is a named container that stores a value a program can use. For example, score = 10 creates a variable called score that holds the number 10. The value can change while the program runs, such as when a player gains points.
Variables make programs flexible and easy to read. Good variable names describe what they store, like playerName or timeLeft. Different types of variables can hold numbers, text or true and false values.
