Exploring JS: JavaScript books for programmers

All of the following books are free to read online. I hope you’ll like them so much that you’ll buy the offline versions.

— Dr. Axel Rauschmayer (author of the 2ality blog)

The books

Speaking JavaScript
- JavaScript for programmers
- No required knowledge (apart from programming)
- Versions of JavaScript: everything, up to and including ECMAScript 5 (ES5)
Exploring ES6
- Version of JavaScript: ECMAScript 6 (also known as ES2015)
Exploring ES2016 and ES2017

Setting up ES6
- Using and configuring Babel 6 in web browsers and on Node.js.

One more book:

Exploring ReasonML and functional programming. ReasonML is probably the FP language that is easiest to learn for JavaScript programmers (and therefore a good way to get started with FP):
- It’s a pragmatic language (based on OCaml), with various “impure” escape hatches (output, mutable state, etc.).
- Its syntax is based on JavaScript’s.
- One of its main goals is good JavaScript interoperability.

Dr. Axel Rauschmayer specializes in JavaScript and web development. He blogs, writes books and teaches classes.

Axel has been writing about the future of JavaScript since early 2011.
