- var orig = Array.prototype[Symbol.iterator];
- delete Array.prototype[Symbol.iterator];
- assert.throws(() => {
- try {
- arr.push(...[3, 4, 5]);
- } finally {
- Array.prototype[Symbol.iterator] = orig;
- }
- }, 'array is not iterable anymore');
- delete Array.prototype.push;
- safePushApply(arr, [3, 4, 5]);
