.toLowerCase not working, replacement function?

Question

The .toLowerCase method is giving me an error when I try to use it on numbers. This is what I have:

var ans = 334;
var temp = ans.toLowerCase();         


        

Answer 1

.toLowerCase function only exists on strings. You can call toString() on anything in javascript to get a string representation. Putting this all together:

var ans = 334;
var temp = ans.toString().toLowerCase();
alert(temp);
