summary | A function is a block of organized, reusable code that performs a specific task. It usually takes some input and produces an output.
Functions can take parameters (also known as arguments), which are variables used to pass data into the function when it's called.
They also have local scope - meaning any variable defined inside them won't affect or be accessible by anything outside of it unless explicitly returned.
The beauty of functions is that they let you abstract and encapsulate functionality, making your code more modular (i.e., breaking down complex processes), easier to read, testable & maintainable.
Functions can return values. A function's primary purpose in most programming languages are performing tasks with a given input or set of inputs returning an output based on this provided information.
Common uses for functions include:
1) Breaking your code into smaller manageable parts
2) Reusing the same piece of logic over multiple times throughout different places without repeating yourself (DRY Principle)
3) Abstraction - hiding complexity behind simpler interfaces.
4) Improving readability and maintainability by separating concerns.
5) Enabling easier debugging & testing due to isolated scope.
In many languages, there are predefined functions available that you can use directly in your code like math operations or string manipulations.
