The wasm runtime wars are heating up! Exciting times :)<p>Really pumped to see this open sourced. And the performance properties look awesome.<p>One interesting thing we’re seeing in this space is sort of two parallel paths emerge: do you want to support JavaScript, or not? An example of the former is CloudFlare and their Workers platform. Hopefully they’ll follow Fastly’s lead and open source their runtime too, but it’s built on top of V8 because they want to support JavaScript. You also gain the additional advantage of all the engineering that Google puts into V8.<p>The other option is stuff like Lucent, wasmer, and wasmtime. By dropping the JavaScript requirement, you can build something that really screams, as seen here. You can partially regain <i>some</i> support via AssemblyScript, the TypeScript subset that compiles to JS. But we haven’t seen JavaScript compile directly to wasm yet because if you want that, well, V8 exists. And you do have to build it all yourself.<p>JavaScript is one of most popular programming programming languages that exists. Time will tell which approach is better, but it’s really fun to watch all of this cool technology explode onto the scene right now.<p>(Disclaimer: I have connections to all of these projects in various ways. Everyone involved in all of them is doing great work.)
