Description

The __iterator__ property was exclusive to the SpiderMonkey engine. Avoid using it as other JavaScript engines do not implement it.

Non-Compliant Code Examples

var a = test.__iterator__;
Foo.prototype.__iterator__ = function() {};
var a = test['__iterator__'];
var a = test[`__iterator__`];
test[`__iterator__`] = function () {};

Compliant Code Examples

var a = test[__iterator__];
var __iterator__ = null;
foo[`__iterator`] = null;
foo[`__iterator__
`] = null;
