Passing Data into Functions

We can pass data into functions using parameters:

js

A parameter acts like a local variable inside the function. However, it takes up the value of the corresponding argument that is passed into the function at the function call.


              12345678
            
function sum(a, b) {
  console.log(a + b);
}

sum(1, 2); // Output: 3
sum(5, 10); // Output: 15
sum(20, 30); // Output: 50
sum(33, 37); // Output: 70

An argument is the actual value passed into a function when calling it:
- Example: In sum(1, 2), the values 1 and 2 are arguments;
A parameter is a placeholder inside the function definition that receives the argument’s value:
- Example: In function sum(a, b), a and b are parameters.

A function in which other functions are called is known as a compound function. A compound function combines smaller functions to accomplish a larger task.
