Package description
The object-keys npm package is a utility that provides a shim for the Object.keys method, which returns an array of a given object's own enumerable property names. It is particularly useful for environments that do not support the native Object.keys method, such as older versions of JavaScript engines.
Shim for Object.keys
Provides a cross-browser implementation of Object.keys to retrieve the keys of an object.
var keys = require('object-keys');
var obj = { a: 1, b: 2, c: 3 };
console.log(keys(obj)); // ['a', 'b', 'c']Lodash is a popular utility library that includes a method called _.keys, which is similar to object-keys. It provides a more robust solution for getting the keys of an object, handling edge cases and supporting a wider range of environments, but it is part of a larger library which may be more than needed if only this functionality is required.
Core-js is a modular standard library for JavaScript, which includes polyfills for many ECMAScript features. It offers a polyfill for Object.keys, among many other features. It is more comprehensive than object-keys, but also larger in size, which might not be ideal for projects looking to minimize dependencies.
