+ * @param {Array} other The other array to compare.
+ * @param {Function} equalFunc The function to determine equivalents of values.
+ * @param {Function} [customizer] The function to customize comparing arrays.
+ * @param {boolean} [isLoose] Specify performing partial comparisons.
+ * @param {Array} [stackA] Tracks traversed `value` objects.

+ * @returns {boolean} Returns `true` if the arrays are equivalent, else `false`.
