+
+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));
+```
+
