                describing my motivations for designing TypL instead of using TS/Flow
              
          
    I am often asked why I don't like a tool like TS (or Flow), and by implication, if I don't like it, the assumption is that I don't want any type aware tooling. That's not true, though.
I have many ideas for what I think type-aware tooling in JS could/should be, and they just happen to diverge significantly enough from TS/Flow that I can't bend into pretzels to fit into that mold.
Instead, I've worked on designing a tool I call TypL that I think addresses my concerns. It's in progress.
Here's my main list of motivations for designing TypL instead of TS/Flow:

I want a system that has both compile-time checking AND run-time checking. TypL's design is to compile away the stuff that it checks at compile time and can verify, and leave in the stuff that it knows needs run-time checking. That way, you don't have to write different sorts of type checking for compile-time and run-time. You get both from one set of typing annotation. It doesn't really seem tha

    React - Functional error boundaries

Thanks to React hooks you have now happily turned all your classes into functional components.
Wait, all your components? Not quite. There is one thing that can still only be implemented using classes: Error boundaries.
There is just no functional equivalent for componentDidCatch and deriveStateFromError yet.
Proposed solution

                How to use profiling in production mode for react-dom 
              
          
    React recently introduced an experimental profiler API. This page gives instructions on how to use this API in a production release of your app.

Profiling in production

React DOM automatically supports profiling in development mode for v16.5+, but since profiling adds some small additional overhead it is opt-in for production mode. This gist explains how to opt-in.
