Simple example code.

<!DOCTYPE html>
<html lang="en">
<body>
  <script>
   let str = 'Hello';
    // substring
    var res1 = str.substring(1);
    console.log(res1);

Delete the first character of string if it is 0

To remove all 0’s at the start of the string:

var s = "0000test";
while(s.charAt(0) === '0')
{
 s = s.substring(1);
}
console.log(s);

The easiest way to strip all leading 0s is:

var s = "00test";
s = s.replace(/^0+/, "");

If it just stripping a single leading 0 character, as the question implies, you could use

s = s.replace(/^0/, "");
