substringAfter( str, search[, fromIndex] ): return the part of a string after a specified substring.
substringBeforeLast( str, search ): return the part of a string before the last occurrence of a specified substring.
substringBefore( str, search ): return the part of a string before a specified substring.
graphemeClusters2iteratorRight( src[, mapFcn[, thisArg]] ): create an iterator which iterates from right to left over grapheme clusters.
graphemeClusters2iterator( src[, mapFcn[, thisArg]] ): create an iterator which iterates over grapheme clusters.
trim( str ): trim whitespace characters from the beginning and end of a string.
truncateMiddle( str, len[, seq] ): truncate a string in the middle to a specified length.
