Great code is readable, bug-free, and maintainable. Modern JavaScript, aka JavaScript Next, makes it much, much easier to write great applications. New features introduced in ES2015 simplify the structure of your JavaScript projects and radically streamline async-oriented tasks like writing reactive applications and microservices.

Get Programming with JavaScript Next introduces you to the new features included in the ES2015-and-later JavaScript releases. You'll learn example by example in 34 short lessons, each designed to drive home a specific skill. The coverage is complete: you'll explore new language syntax, declarations, and data types. You'll structure code with modules, replace callbacks with promises, and use classes instead of constructors. Every time you turn a page, complete an exercise, or study a carefully crafted illustration, you'll be one step closer to JavaScript mastery.
