WebAssembly is an exciting new language that many JavaScript engines have added support for. WebAssembly promises to make it much easier to compile languages like C and C++ to something that runs in the browser. However, I’m most excited about the ability to write optimized custom arithmetic and buffer manipulations, like, say, fast decimal floating point arithmetic in JavaScript without having to wait for TC39 to get around to it. In this article, I’ll show you how to get a couple rudimentary WebAssembly examples running in Node.js, and run a couple trivial benchmarks to show the performance impact.
