Description

https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Functions...
From ES6/ES2015, default parameters is in the language specification.

function my_function(item, new = false) {
  // Code
}

Konqueror does not support this.
If I use it in my jquery code, javascript fails completely within konqueror.
