func_documentation_string: Returns the first n elements of an object. If the object is an array, and only one items is retrieved,
  that item will be returned, rather than an array.
  @param {Object} o The object to operate on.
  @param {Number=} [n=1] The number of elements to return
  @return {Array<*>} The first n elements of the array.
