Functions in programming are like magic boxes. They take in information, do something with it, and then give you back a result. Here are some important things to know about them:
Inputs and Outputs: Functions usually take inputs, which we call parameters, and return outputs. For example, if you have a function that adds two numbers, you put in those numbers, and it gives you the answer.
Encapsulation:
A function wraps up a specific task or set of instructions.
This means you can use it without needing to understand exactly how it works.
For instance, you might use a function called calculateArea(radius) without knowing how it figures out the area of a circle.
Reusability: One of the coolest things about functions is that you can use them over and over again. You can create a function once and then call it many times in your program. This saves you time and makes your code easier to maintain.
Modularity: Functions help break a big program into smaller, manageable parts. Each function can focus on one specific task, making it easier to fix issues and understand the whole program.
Naming:
Choosing good names for your functions is very important.
A function’s name should clearly show what it does, like sortList() or fetchData().
In short, functions are super important in programming. They help keep the code clean, efficient, and organized!
