@teamteanpm2024/reprehenderit-magni-id

An ES5 mostly-spec-compliant Object.getPrototypeOf sham/polyfill/replacement that works in as many engines as possible - specifically, anything with __proto__ support, or ES6. Built-in types will also work correctly in older engines.

This package implements the es-shim API interface. It works in an ES3-supported environment and complies with the spec.

Example

1var getPrototypeOf = require('@teamteanpm2024/reprehenderit-magni-id');
2var assert = require('assert');
3
4assert.equal(getPrototypeOf(true), Boolean.prototype);
5assert.equal(getPrototypeOf(42), Number.prototype);
6assert.equal(getPrototypeOf(''), String.prototype);
7assert.equal(getPrototypeOf(/a/g), RegExp.prototype);
8assert.equal(getPrototypeOf(new Date()), Date.prototype);
9assert.equal(getPrototypeOf(function () {}), Function.prototype);
10assert.equal(getPrototypeOf([]), Array.prototype);
11assert.equal(getPrototypeOf({}), Object.prototype);

1var getPrototypeOf = require('@teamteanpm2024/reprehenderit-magni-id');
2var assert = require('assert');
3/* when Object.getPrototypeOf is not present */
4delete Object.getPrototypeOf;
5var shimmed = getPrototypeOf.shim();
6assert.equal(shimmed, getPrototypeOf.getPolyfill());
7
8assert.equal(Object.getPrototypeOf(true), Boolean.prototype);
9assert.equal(Object.getPrototypeOf(42), Number.prototype);
10assert.equal(Object.getPrototypeOf(''), String.prototype);
11assert.equal(Object.getPrototypeOf(/a/g), RegExp.prototype);
12assert.equal(Object.getPrototypeOf(new Date()), Date.prototype);
13assert.equal(Object.getPrototypeOf(function () {}), Function.prototype);
14assert.equal(Object.getPrototypeOf([]), Array.prototype);
15assert.equal(Object.getPrototypeOf({}), Object.prototype);

1var getPrototypeOf = require('@teamteanpm2024/reprehenderit-magni-id');
2var assert = require('assert');
3/* when Object.getPrototypeOf is present */
4var shimmedGetPrototypeOf = getPrototypeOf.shim();
5assert.equal(shimmedGetPrototypeOf, Object.getPrototypeOf);
6assert.equal(Object.getPrototypeOf([]), Array.prototype);
