- * Splits a string into an array of strings using a regex or string separator. Matches of the
- * separator are not included in the result array. However, if `separator` is a regex that contains
- * capturing groups, backreferences are spliced into the result each time `separator` is matched.
- * Fixes browser bugs compared to the native `String.prototype.split` and can be used reliably
- * cross-browser.
- * @param {String} str String to split.
- * @param {RegExp|String} separator Regex or string to use for separating the string.
- * @param {Number} [limit] Maximum number of items to include in the result array.
- * @returns {Array} Array of substrings.
- * @example
- *
- * // Basic use
- * split('a b c d', ' ');
- * // -> ['a', 'b', 'c', 'd']
- *
- * // With limit
- * split('a b c d', ' ', 2);
- * // -> ['a', 'b']
- *
- * // Backreferences in result array
- * split('..word1 word2..', /([a-z]+)(\d+)/i);
