stop function execution in javascript code example

Example 1: javascript stop execution

// EXAMPLE
throw new Error("This is your custom error message");

/*
SYNTAX
throw new Error("<your-custom-message>");
*/

Example 2: 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
