• Get up to date on ECMAScript through ES2019, including classes, promises, async/await, proxies, iterators, generators, symbols, modules, and spread/rest operators.
• Delve into fundamental web development concepts such as the document object model (DOM), browser object model (BOM), events, forms, JSON, error handling, and web animation.
• Learn about advanced browser APIs such as geolocation, web workers, service workers, fetch, atomics, streams, message channels, performance timelines, and web cryptography.
• Work hands-on with hundreds of working code examples that demonstrate concepts clearly and concisely.

Even if you think you know JavaScript, new ES releases bring big changes that will affect the way you work. For a professional-level update that doesn’t waste time on coding fundamentals, Professional JavaScript for Web Developers is the ultimate resource to bring you up to speed.
