Enumerate properties that will not enumerate in older browsers (i.e. IE 8 and below).
npm install enum-bug
Note: use add --save if you are using npm < 5.0.0
import enumBug from 'enum-bug';
const obj = {
hello: 'not a bugged property',
constructor: 'bugged property',
hasOwnProperty: 'bugged property',
isPrototypeOf: 'bugged property',
propertyIsEnumerable: 'bugged property',
toLocaleString: 'bugged property',
toString: 'bugged property',
valueOf: 'bugged property',
goodbye: 'another normally enumerated property',
};
enumBug(obj, prop => {
console.log(`${prop} is bugged.`);
});
By executing the code in an environment that contains an object enumeration bug (i.e. Internet Explorer 8 and below), the result will be
// console
=> constructor is bugged
=> hasOwnProperty is bugged
=> isPrototypeOf is bugged
=> propertyIsEnumerable is bugged
=> toLocaleString is bugged
=> toString is bugged
=> valueOf is bugged
The bugged properties are:

If the environment supports object property enumeration, no properties are enumerated.
