Question

I have a function that looks like this:

function MyFunction() {

  //do some work

  if (SomeCondition === true) {
     //do some work
     FunctionToCall();
  }
  //do some more work
}

function FunctionToCall() {...}

If ever I call the FunctionToCall(), I don’t want to continue with do some more work. Do I need to put a return true or return false statement after the FunctionToCall(); statement? It seems to work with both.

Thanks.

As you said, you would need to put a return after the call to FunctionToCall. By the sound of it, it doesn’t matter what you return (this will return undefined):

if (SomeCondition === true) {
    //do some work
    FunctionToCall();
    return;
}

If you did care about the result of FunctionToCall, you could return the value returned from that:

return FunctionToCall();

Alternatively, you could use an else, and not bother with a return statement (this will return undefined too):

if (SomeCondition === true) {
    //do some work
    FunctionToCall();
}
else {
    //do some more work
}
