return stop function javascript 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: stop a function javascript

function func() {
  if (conditionToStopFunction)
    return; //Nothing after return will be executed
  
  console.log("Hello World"); //This will not be executed if 'conditionToStopFunction' is true
}

Example 3: c# stop loop in method

/* There is another way to break out of a loop if you use 
   the return command inside a method/function */

class MainClass {
 public static void Main (string[] args) {
   UnlockDoor();

  // after it hits the return statement, 
  // it will move on to this method
   PickUpSword();
 }

 static bool UnlockDoor()
 {
   bool doorIsLocked = true;

   // this code will keep running
   while (doorIsLocked)
   {
     bool keyFound = TryKey();

      // eventually if this stopping condition is true,
      // it will break out of the while loop
     if (keyFound)
     {
// this return statement will break out of the entire method
      return true;
     }
   }
   return false;
 }
}
