Push an array of items into an array, while being robust against prototype modification.

|
## Getting started
|
|
|
|
```sh
|
|
npm install --save safe-push-apply
|
|
```
|
|
|
|
## Usage/Examples
|
|
|
|
```js
|
|
var safePushApply = require('safe-push-apply');
|
|
var assert = require('assert');
|
|
|
|
var arr = [1, 2, 3];
|
|
|
|
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]);
|
|
|
|
assert.deepEqual(arr, [1, 2, 3, 3, 4, 5]);
