this._reset() is undefined

[HipsterBrown]

I was going through the Human JavaScript online videos when I encountered an error during 4-5 "Creating a collection for users".

TypeError: 'undefined' is not a function (evaluating 'this._reset()')

This error is traced back to the Collection function within ampersand-collection.js

function Collection(models, options) {
  options || (options = {});
  if (options.model) this.model = options.model;
  if (options.comparator) this.comparator = options.comparator;
  if (options.parent) this.parent = options.parent;
  this._reset();
  this.initialize.apply(this, arguments);
  if (models) 
    this.reset(models, extend({
      silent: true
    }, options));
}

I think it may have something to do with the recent update to Underscore to 1.7.0, which apparently had some breaking changes. I tried rolling back the dependency to 1.6.0 but it is still breaking.

Any help would be great.

Ok nevermind on the Underscore thing. For some reason the this._reset() is called before defined further down in the file. None of the private or public functions defined in the extend, after creating the Collection constructor. Still digging.

@HipsterBrown, were you using new when instantiating your collection? It sounds like that might have been missing.

I'll check it out. It's been a while since I've been working on that project. Thanks for the tip.

Oh, yes. You were right in the first comment. Issue is solved.
