how to return out of the entire function js code example

Example 1: js break out of a function

By using 'return;':

function myfunction(){
   if(a == 'stop') 
      return;  //returns Void, ending function
}

Does not work when using a Conditional operator:

let result =  1 == 2   ?  "YES" : return;  //<--- throws error

Example 2: what does return do in javascript

function add(a, b) {
  return a + b; //Return stops the execution of this function
}

var sum = add(5, 24); //The value that was returned got but inside the variable sum
