Monorepos: Please don’t!

“ The frank reality is that, at scale, how well an organization does with code sharing, collaboration, tight coupling, etc. is a direct result of engineering culture and leadership, and has nothing to do with whether a monorepo or a polyrepo is used.

WebAssembly Is Fast: A Real-World Benchmark of WebAssembly vs. ES6

“ Wasm is about 30% faster than asm.js / JavaScript. On desktop chrome, this is mostly true! I want to say “mostly”, as we noticed it was about 40% faster not using closure compiler. Personally, I have not seen many web apps / libraries use Closure compiler day-to-day, but running it through closure gets us to the expected 30%. Though on all other configurations, this can’t really be considered true. Mobile Chrome is about 60% faster, mobile and desktop Firefox is insanely faster by about 90%, mobile and desktop Safari is only bit faster by about 20%.”
