.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

It's not an error. Javascript will gladly convert a number to a string when a string is expected (for example parseInt(42)), but in this case there is nothing that expect the number to be a string.

Here's a makeLowerCase function. :)

function makeLowerCase(value) {
  return value.toString().toLowerCase();
}
