Delete char from String

I have a string like this: 0000323530, I need to eliminate all the 0 on the left until it reaches number 3 (for example, it could be another number ALWAYS different from 0)

Just replace the beginning zeros with nothing using regex.

var num = "0000323530"
console.log(num.replace(/^0+/, ""))

You can use regex for that, here is an example:

function removeLeadingZeros(str){
    return str.replace(/^0+/, "")
}

console.log(removeLeadingZeros("0000323530"));

^ stands for the start of the string

0 stands for the character 0

+ stands for one or multiple of the previous char or group

which means that this regex will match all the zeros at the start of the string.
