Return Global Variable from Javascript Method [closed]

Answer 1

There doesn't seem to be much point in returning a global variable, the function can just set it and other functions reference it.

var setGlobal = (function(global) {
  return function(value) {
    global.someVarName = value;
  }
}(this));

var readGlobal = (function(global) {
  return function() {
    return global.someVarName;
  }
}(this));

setGlobal('foo');
alert(readGlobal()); // foo
alert(someVarName);  // foo
