SCRIPT1006: Expected ')'

Question

In the function below, IE says that \')\' is missing:

function padZeros(num, size = 4) {
    var s = num+\"\";
    while (s.length < size) {
        s = \"0\"         


        

Answer 1

This is happening because you are trying to run the Javascript ES6 code on non supported IE browser.

ECMAScript 6, also known as ECMAScript 2015, is the latest version of the ECMAScript standard. ES6 is a significant update to the language, and the first update to the language since ES5 was standardized in 2009.

Please go through the below docs for more details

Funtion with default value : https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/Default_parameters#Syntax

Supported Browser Lists : https://kangax.github.io/compat-table/es6/

Here is the update code for all browsers

function padZeros(num, size) {
 var s = num+"";
 while (s.length < size) {
  s = "0" + s;
 }
 return s;
}
padZeros(10,4)/*10 is your num and 4 is your pad size*/
