Converts all characters in this string to lower case. If the string is already in all lower case, this method returns this
.
'ALPHABET'.toLowerCase(); // 'alphabet' 'abc'.toLowerCase(); // 'abc'
This function uses the language independent Unicode mapping and thus only works in some languages.
// TODO(floitsch): document better. (See EcmaScript for description). String toLowerCase();
