/** * This function is like `baseIndexOf` except that it accepts a comparator. * * @private * @param {Array} array The array to inspect. * @param {*} value The value to search for. * @param {number} fromIndex The index to search from. * @param {Function} comparator The comparator invoked per element. * @returns {number} Returns the index of the matched value, else `-1`. */function baseIndexOfWith(array, value, fromIndex, comparator) {  var index = fromIndex - 1,      length = array.length;
