Calling a 'sibling' function

Question

I have some code that looks like this

var viewService = function () {
   ...
   return {
      ...
      ,isAbsolute: function (view) { ... }
      ...
      ,removeAbsoluteViews: function () { ... }
      }
   };
};

What I'd like to do is call isAbsolute from removeAbsoluteViews. When I try to do that like this

if (isAbsolute(v) === false) { ... }

I get an error saying isAbsolute is not defined. How can I do this?

if `if (this.isAbsolute(v) === false)` didn't work, it would be because `removeAbsoluteViews` didn't have the correctly scoped `this`. You should also indicate how you're calling `removeAbsoluteViews`. The following example shows how `this` scoping can fail: `setTimeout(viewService.removeAbsoluteViews, 50);` — I-Lin Kuo, Jun 06 '14 at 14:43

Since you return an object you can use the `this` keyword:

if (this.isAbsolute(v) === false) { ... }

You can also declare it like so (without the `this` keyword):

var viewService = function () {

  function isAbsolute (view) { ... }

  function removeAbsoluteViews () { 
    if (isAbsolute(v) === false) { ... }
  }

  ...

  return {
    isAbsolute: isAbsolute,
    removeAbsoluteViews: removeAbsoluteViews
  };
};
