The State of WebAssembly

on YouTube ↗37m

" summary

WebAssembly is positioned as a compiler target and universal VM rather than a JavaScript replacement, with concrete numbers and demos: running a PHP interpreter in Wasm yields about 80× slower than native, Blazor front ends run roughly Blazor 4× slower than vanilla JS, and AssemblyScript can be AssemblyScript 2× faster than JavaScript. Practical deployments include Shopify and Cloudflare running user plugins in Wasm, Unity porting games successfully while Unreal removed support, and Chrome telemetry showing about 4.5% of pages loading Wasm.
