Iterate JSON Object in Premiere.jsx using JSON2.js

I found the solution here:

https://community.adobe.com/t5/photoshop/parsing-json-in-jsx-referenceerror-object-keys-is-not-a-function/m-p/8610669?page=1

I literally had to define the Object.keys function. 

This feels like an obsolete and primitive solution but its the only thing I found that worked. 

if (!Object.keys) {

			Object.keys = (function () {
			
				'use strict';
			
				var hasOwnProperty = Object.prototype.hasOwnProperty,
			
					hasDontEnumBug = !({toString: null}).propertyIsEnumerable('toString'),
			
					dontEnums = [
			
					'toString',
			
					'toLocaleString',
			
					'valueOf',
			
					'hasOwnProperty',
			
					'isPrototypeOf',
			
					'propertyIsEnumerable',
			
					'constructor'
			
					],
			
					dontEnumsLength = dontEnums.length;
			
				return function (obj) {
			
				if (typeof obj !== 'object' && (typeof obj !== 'function' || obj === null)) {
			
					throw new TypeError('Object.keys called on non-object');
			
				}
			
				var result = [], prop, i;
			
				for (prop in obj) {
			
					if (hasOwnProperty.call(obj, prop)) {
			
					result.push(prop);
			
					}
			
				}
			
				if (hasDontEnumBug) {
			
					for (i = 0; i < dontEnumsLength; i++) {
			
					if (hasOwnProperty.call(obj, dontEnums)) {
			
						result.push(dontEnums);
			
					}
			
					}
			
				}
			
				return result;
			
				};
			
			}());
			
		}
