ECMAScript 6 in WebKit
ES6 brings a lot of new and interesting language features to JavaScript. ES6 has learned from many of JavaScript’s past mistakes and has crafted new language features that have clearer and easier to understand semantics. let and const are examples of this; they are block scoped declarations and thus not prone to the common errors caused by misunderstanding var scoping semantics. ES6 also includes

Polyfill · Babel
🚨 As of Babel 7.4.0, this package has been deprecated in favor of directly including core-js/stable (to polyfill ECMAScript features): If you are compiling generators or async function to ES5, and you are using a version of @babel/core or @babel/plugin-transform-regenerator older than 7.18.0, you must also load the regenerator runtime package. It is automatically loaded when using @babel/preset-e

Proxies enable you to intercept and customize operations performed on objects (such as getting properties). They are a meta programming feature.
