Preconditions
Definition
Preconditions are conditions or requirements that must be met before a certain action or function can be executed. They ensure that the necessary conditions are in place for the code to run correctly.
Analogy
Think of preconditions as the rules you have to follow before playing a game. Just like you need to set up the game board and understand the rules before starting, preconditions establish what needs to be true before executing a piece of code.
