[TIL] 20201203 Introducing Functions

Function

• Reusable procedures
• Allows us to write reusable, modular code
• We define a "chunk" of code that we can then excute at a later point.

 

 

How to define a function

function functionName() {
    //code
}

 

 

 

Argument

• Inputs that functions accept
• Syntax

//argument === parameter

function functionName(parameter){
    //code
}

• Functions with multiple arguments

function functionName(param1, paramN){
    //code
}

//*** ORDER of parameters MATTERS ***//

 

 

 

Return 

• Output of the function
• Ends function execution and specifies the value to be returned by that function.
