JavaScript string object introduction instance of the toLowerCase method (for converting letters toLowerCase)

JavaScript toLowerCase method

The toLowerCase method is used to convert (English) strings toLowerCase and return the converted string. The syntax is as follows:

str_object.toLowerCase()

Example of the toLowerCase method

<script language="JavaScript">

var str = "AaBbCc";

alert( str.toLowerCase() );

</script>

Run the example and a prompt pops up with aabbcc

ToLocaleLowerCase method

The toLocaleLowerCase method is basically the same as toLowerCase, which converts strings toLowerCase locally. Only a few languages, such as Turkish, have locally-specific case mappings.
