Simple Guide to Functions and Procedures

In programming, functions and procedures are like tools that help us organize our code. They let us create reusable blocks of instructions. Here's how you can define these tools in a few popular programming languages:

1. Python

def my_function(parameter):
    # Code to run
    return result

• Example:

  def add_numbers(a, b):
      return a + b
  

2. JavaScript

function myFunction(parameter) {
    // Code to run
    return result;
}

• Example:

  function multiply(a, b) {
      return a * b;
  }
  

3. Java

returnType myFunction(parameter) {
    // Code to run
}

• Example:

  int subtract(int a, int b) {
      return a - b;
  }
  

When you use functions and procedures, your code looks cleaner and is easier to fix!
