docs: Invokes the callback 'f' for every property the object contains. If the callback returns true, the
  loop is broken and false is returned; otherwise true is returned.
  @param {Object} o The object to operate on.
  @param {Function} f The callback to invoke for each item within the object
  @returns {Boolean} True if none of the callback invocations returned false.
