My personal discoveries: * Websockets + JSON is 8x faster than HTTP and less error prone, so I worked on HTTP elimination in my app to great success. It has all the advantages of gRPC but you don’t have to deal with protobuf. * Browser performance. My OS GUI loads in 200ms on Chrome and 300ms on Edge with full state restoration, which is faster than the GPU can visually render the output to screen. The performance tab in the browser dev tools is amazing. * When you have a solid foundation you can scale an application in any direction very quickly. In the browser I am working directly to the DOM and treating it no differently than the file system: a big giant globally available living tree model. In the past week I wrote a command terminal that works in the browser with autocomplete and ANSI color support and it took about 10-12 hours because the application is mature. * I see many new developers struggle with async functions and promise chains. I made a commitment to myself to avoid such struggles and fallback to old style callbacks which are more verbose and less clever.
