  15
  16 ```js
  17 var GetIntrinsic = require('get-intrinsic');
  18 var assert = require('assert');
  19
  20 // static methods
  21 assert.equal(GetIntrinsic('%Math.pow%'), Math.pow);
  22 assert.equal(Math.pow(2, 3), 8);
  23 assert.equal(GetIntrinsic('%Math.pow%')(2, 3), 8);
  24 delete Math.pow;
  25 assert.equal(GetIntrinsic('%Math.pow%')(2, 3), 8);
  26
  27 // instance methods
  28 var arr = [1];
  29 assert.equal(GetIntrinsic('%Array.prototype.push%'), Array.prototype.push);
  30 assert.deepEqual(arr, [1]);
  31
  32 arr.push(2);
  33 assert.deepEqual(arr, [1, 2]);
  34
  35 GetIntrinsic('%Array.prototype.push%').call(arr, 3);
  36 assert.deepEqual(arr, [1, 2, 3]);
  37
  38 delete Array.prototype.push;
  39 GetIntrinsic('%Array.prototype.push%').call(arr, 4);
  40 assert.deepEqual(arr, [1, 2, 3, 4]);
  41
  42 // missing features
  43 delete JSON.parse; // to simulate a real intrinsic that is missing in the environment
  44 assert.throws(() => GetIntrinsic('%JSON.parse%'));
  45 assert.equal(undefined, GetIntrinsic('%JSON.parse%', true));
  46 ```
