Solution 2:
Use either toLowerCase or toLocaleLowerCase methods of the String object. The difference is that toLocaleLowerCase will take current locale of the user/host into account. As per § 15.5.4.17 of the ECMAScript Language Specification (ECMA-262) , toLocaleLowerCase… …works exactly the same as toLowerCase except that its result is intended to yield the correct result for the host environment’s current locale, rather than a locale-independent result. There will only be a difference in the few cases (such as Turkish) where the rules for that language conflict with the regular Unicode case mappings. Example:
var lower = 'Your Name'.toLowerCase();

Solution 4:
<script type="text/javascript">
var yourstring = 'Your Name'
var lowercase = yourstring.toLowerCase();
document.write('original string:<b> ' + yourstring + '</b><br>');
document.write('converted sting <b>' + lowercase + '</b>');
</script>

Solution 5:
consuming a plugin, and was confused why I was getting a "extension.tolowercase is not a function" JS error.
onChange: function(file, extension)
{
alert("extension.toLowerCase()=>" + extension.toLowerCase() + "<=");

Which produced the error "extension.toLowerCase is not a function" So we tried this piece of code, which revealed the problem!
alert("(typeof extension)=>" + (typeof extension) + "<=");;
