| Get and robustly cache all JS language-level intrinsics at first require time. | |
| See the syntax described [in the JS spec](https://tc39.es/ecma262/#sec-well-known-intrinsic-objects) for reference. | |
| ## Example | |
| ```js | |
| var GetIntrinsic = require('get-intrinsic'); | |
| var assert = require('assert'); | |
| // static methods | |
| assert.equal(GetIntrinsic('%Math.pow%'), Math.pow); | |
| assert.equal(Math.pow(2, 3), 8); | |
| assert.equal(GetIntrinsic('%Math.pow%')(2, 3), 8); | |
| delete Math.pow; | |
| assert.equal(GetIntrinsic('%Math.pow%')(2, 3), 8); | |
| // instance methods | |
| var arr = [1]; | |
| assert.equal(GetIntrinsic('%Array.prototype.push%'), Array.prototype.push); | |
| assert.deepEqual(arr, [1]); | |
| arr.push(2); | |
| assert.deepEqual(arr, [1, 2]); | |
| GetIntrinsic('%Array.prototype.push%').call(arr, 3); | |
| assert.deepEqual(arr, [1, 2, 3]); | |
| delete Array.prototype.push; | |
| GetIntrinsic('%Array.prototype.push%').call(arr, 4); | |
| assert.deepEqual(arr, [1, 2, 3, 4]); | |
| // missing features | |
| delete JSON.parse; // to simulate a real intrinsic that is missing in the environment | |
| assert.throws(() => GetIntrinsic('%JSON.parse%')); | |
| assert.equal(undefined, GetIntrinsic('%JSON.parse%', true)); | |
| ``` | |
| ## Tests | |
| Simply clone the repo, `npm install`, and run `npm test` | |
