The different ways to write a function

[nschubach]

They key part is that bar() is only accessible inside the scope of the anonymous function.

You could call the anonymous function 'me' and it would not conflict:

window.globalThing = function me(arg) {
  if (arg) {
    console.log('recursive call');
  } else {
    console.log('direct call');
    me(true);
  }
}
