SCRIPT1006: Expected ')' in IE (no other browser)

I have an issue with a plugin that is causing a bug in IE but not in any other browser.

The bug error is:

SCRIPT1006: Expected ')'
filename.js (449,35)

Looking up this line in the script I can see:

   function dependanceLookup(_el, ev = false) {
      if (......etc etc

From what I can tell, this is due to ES6 (probably wrong as i'm not fluent in javascript).

Is there a way to change this line so it will work in IE? I haven't posted the whole code as it's from a paid plugin and I don't want anyone copying their code etc.

The fix was :

function dependanceLookup(_el, ev) { ev = !!ev;

`ev = false` in the function declaration, there's no defaulting parameters like that in vanilla js – Jorg Jan 09 '20 at 12:28

It is the [default parameter](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/Default_parameters) that is not supported `ev = false)` in ES<6 – mplungjan Jan 09 '20 at 12:28
Remove `ev = false` default parameter and assign it at the beginning of the function body. – Roberto Zvjerković Jan 09 '20 at 12:29

`function dependanceLookup(_el, ev) { ev = !!ev; ...` – mplungjan Jan 09 '20 at 12:44
