/**
 * The inverse of `_.pairs`; this method returns an object composed from arrays
 * of property names and values. Provide either a single two dimensional array,
 * e.g. `[[key1, value1], [key2, value2]]` or two arrays, one of property names
 * and one of corresponding values.
 *
 * @static
 * @memberOf _
 * @alias object
 * @category Array
 * @param {Array} props The property names.
 * @param {Array} [values=[]] The property values.
 * @returns {Object} Returns the new object.
 * @example
 *
 * _.zipObject([['fred', 30], ['barney', 40]]);
 * // => { 'fred': 30, 'barney': 40 }
 *
 * _.zipObject(['fred', 'barney'], [30, 40]);
 * // => { 'fred': 30, 'barney': 40 }
