A peek into the WebAssembly Browser Preview
Following the introduction of asm.js, we have been working with other browser vendors including Mozilla, Google, Apple, along with the rest of the WebAssembly community group, to push the performance boundary of the web with WebAssembly. WebAssembly is a new, portable, size- and load-time-efficient binary compiler target, which promises near-native performance on the web. As

WebAssembly and its platform targets
When talking about WebAssembly, one of the things that often confuses people is the lack of a great analogy for the various platform targets that WebAssembly supports. This ends up being a bit important as it dictates whether your WebAssembly code will (not) work with another bit as it all
Why is WebAssembly a second-class language on the web? – Mozilla Hacks - the Web developer blog
This post is an expanded version of a presentation I gave at the recent WebAssembly CG meeting in Munich. WebAssembly has come a long way since its first release in 2017. The 1.0 version of WebAssembly was already a great fit for low-level languages like C and C++, and immediately enabled many new kinds of applications to efficiently target the web.

A practical guide to WebAssembly memory | radu's blog
Memory in WebAssembly is one of the topics that creates confusion for newcomers, particularly for those with experience in languages with memory management features like garbage collection, such as JavaScript, Go, or Java. In this article we explore using memory in WebAssembly in various scenarios - passing JavaScript arrays to Rust and AssemblyScript modules, checking for some basic memory leaks using Valgrind, or exchanging strings between runtimes and modules using Wasmtime.
