"0123Test" is a better number-containing string for testing, to catch out things that try to interpret the string as a number first and then as a string if that fails. For example, JS's insane parseInt function will give you 123 for "0123Test".

Wow, I learned something in here and I was just "trolling" in the test thread!

Thanks!

   > parseInt("0123Test")
   123
   > 0123
   83

parseInt is actually the adult in the room

>>_-____+(OP)
That leading 0 is also useful for the things that try to interpret the string as number first and are able to understand octal.

>>yread+M2
In a way. The convention is that 0123 is "123" in octal.

>>TeMPOr+Q2
Yes, I know that's why I even tried it in console as I was a bit surprised that parseInt doesn't do octal.

Why does js even support octal? I never found octal particularly useful. Speak hexadecimal or die

>>yread+e7
Because C does.

    > parseInt('0123Test', 8)
    83

you could do it like this, otherwise it uses the default value for the base parameter.
