get-intrinsic 
Get and robustly cache all JS language-level intrinsics at first require time.
See the syntax described in the JS spec for reference.
Example
1var GetIntrinsic = require('get-intrinsic');
2var assert = require('assert');
3
4// static methods
5assert.equal(GetIntrinsic('%Math.pow%'), Math.pow);
6assert.equal(Math.pow(2, 3), 8);
7assert.equal(GetIntrinsic('%Math.pow%')(2, 3), 8);
8delete Math.pow;
9assert.equal(GetIntrinsic('%Math.pow%')(2, 3), 8);
10
11// instance methods
12var arr = [1];
13assert.equal(GetIntrinsic('%Array.prototype.push%'), Array.prototype.push);
14assert.deepEqual(arr, [1]);
15
16arr.push(2);
17assert.deepEqual(arr, [1, 2]);
18
19GetIntrinsic('%Array.prototype.push%').call(arr, 3);
20assert.deepEqual(arr, [1, 2, 3]);
21
22delete Array.prototype.push;
23GetIntrinsic('%Array.prototype.push%').call(arr, 4);
24assert.deepEqual(arr, [1, 2, 3, 4]);
25
26// missing features
27delete JSON.parse; // to simulate a real intrinsic that is missing in the environment
28assert.throws(() => GetIntrinsic('%JSON.parse%'));
29assert.equal(undefined, GetIntrinsic('%JSON.parse%', true));Tests
