slice(beginIndex, endIndex)
string.slice(1, -1)An alternative approach to removing the characters from a string is to use the substring method.
substring(indexStart, indexEnd)
yourString.substring(1, yourString.length-1);Note: Both methods do not modify the original string.

<!DOCTYPE html>

// slice
const res = str.slice(1, -1);
console.log(res);
// substring
const nres = str.substring(1, str.length - 1);
console.log(nres);
</script>
</body>
</html>

You can remove the first character of a string using substring:
var s1 = "foobar";
var s2 = s1.substring(1);
alert(s2); // shows "oobar"To remove all 0’s at the start of the string:
var s = "0000test";
while(s.charAt(0) === '0')
{
s = s.substring(1);
