I know it is related to Remove first character from a string if it is a ma but in this case that solution doesn't work for me. Maybe its because now I'm dealing with a number. Simply I want javascript to remove 0 from 08 but don't touch 10; only remove 0 when it is the first character.

This solution doesn't work: replace(/^0/, "")

• Beucase, apparently he is trying to call it on a Number i think. – mic4ael Commented Nov 5, 2015 at 12:10
• 4 use parseInt(). Integers dont have a leading zero. – pmayer Commented Nov 5, 2015 at 12:12
• parseInt("08", 10); – Rahul Tripathi Commented Nov 5, 2015 at 12:12
• What do you mean, "it doesn't work"? Are you calling .replace() on a string that starts with "08"? If so, how is the result incorrect? – Tim Pietzcker Commented Nov 5, 2015 at 12:25

You can try this:

alert("08".replace(/^0+/, ''));

DEMO

And if you are dealing with numbers then you can use parseInt() function.

Easy way with regex :

^0+(?!$)

and feel free to use String replaceFirst function.
