How to convert number leading zero to string and retain the original number

I'm trying to convert number lead by 0 to string.

for example

var x = 01127160037

but when I convert it to string, it become 157081631

<script>
function myFunction() {
  var x = 01127160037;
  var res = x.toString();
  console.log(res)
}
myFunction();
</script>

I'm expecting to get actual result as "01127160037" in string.

With leading zero, you use octal numbers. To get decimals, you need to convert back to octals and take this string.

If you got a value which can not be an octal number, check if the stringed value contains eight or nine and take this value without conversion instead.

const convert = n => '0' + (/[89]/.test(n.toString())
        ? n.toString()
        : n.toString(8)
    );

console.log(convert(01127160037));
console.log(convert(01127160038));
