At its core, a function is a block of code that takes input, performs a specific task, and returns output. Think of it as a recipe: you provide the ingredients (input), follow a set of instructions (function), and get a desired outcome (output). Functions can be thought of as self-contained modules that can be called upon multiple times within a program without having to rewrite the same code repeatedly. This modular approach makes code more maintainable, scalable, and efficient.

• Reusability: Allowing code to be reused across multiple parts of a program.
