Frequently asked

What is core-js?โ€บ
Core-js is a modular standard library for JavaScript that provides polyfills and features that JavaScript engines don't have by default. It includes basic utilities, ECMAScript features, and additional stable proposals that are useful for modern JavaScript development.
What are the advantages of using core-js?โ€บ
Core-js offers several advantages including cross-browser compatibility, easy integration with build tools and bundlers, and a wide range of polyfills for modern JavaScript features. By using core-js, developers can ensure a consistent experience across different platforms and devices, and utilize the latest language features without sacrificing support for older engines.
Does core-js support ES6 features?โ€บ
Yes, core-js fully supports ECMAScript 6 (ES6) features as well as later editions of the standard, and also includes some experimental features and proposals that might become part of future standards. By utilizing core-js, developers can use modern ES6 features and be assured of compatibility across engines that do not natively support them.
How can I include core-js in my project?โ€บ
You can include core-js in your project either by installing it via npm or yarn (`npm install core-js` or `yarn add core-js`) and then importing the required polyfills in your code, or by using a CDN to load the library directly in your HTML file. Once included, the polyfills will automatically patch the environment, providing the missing features.
How does core-js handle conflicts between native implementations and polyfills?โ€บ
Core-js is designed to avoid conflicts between its polyfills and native implementations of the same features. When a polyfill is loaded, core-js checks if the native implementation is already available and compliant with the standard. If so, the native implementation is used; otherwise, core-js replaces or extends the native feature with its polyfill to ensure a consistent behavior across environments.
