WebAssembly: a binary format for the web


WebAssembly (short: wasm) is a new binary format for the web, created by Google, Microsoft, Mozilla and others. It will be used for performance critical code and to compile languages other than JavaScript (especially C/C++) to the web platform. It can be seen as a next step for asm.js [3].


Announcing “Exploring ES6”

I’m glad to announce that the first version of my book “Exploring ES6” is finally finished! It was much more work than I anticipated – the PDF has over 460 pages! I’m really happy with how it turned out.

The complete contents of the book are available online, for free. The ebook version (PDF, EPUB, MOBI) costs about $30 (depending on the VAT in your country, you can pay more to support my work).

Exploring ES6 is a living book: you can buy it now and will receive free updates until it is completely done. That may take a while, possibly until 2016. Once the book is done, there will also be a print version. New material will often be published on 2ality, before it is added to the book.
