A simple, solid type system that doesn't get confused while you refactor your code. Change the right field in the right record, and leave the superficially similar ones alone!
Works across files too.

Ah, the power of having proper language constructs to handle return values and exceptions in both sync and async manner without the need of let variables and try/catches.
Just another day in ReScript 😎
Did you know that in ReScript you can pattern match directly on `await`, and that you can handle exceptions in the same switch?
Can't be overstated what a productivity multiplier this is given how cumbersome error handling in async/await can be.
Also, notice `Ok()` and

Diffing clean, readable JavaScript output means that you can make giant ReScript changes with a high confidence rate of having introduced no migration bug.
This is the technique we’ve used internally to migrate high six digits number of lines too.

More importantly, our compilation saves intermediate artifacts as checkpoints! This means:
- If your compilation gets shut down halfway, we pick up from where we left. No staleness or weird state
- We don't ever run out of memory during compilation

Something exciting just landed in the pre-release version of the

Check out this example. All of this is without the compiler running. This will hopefully make a big difference when writing ReScript.

Relay looks beautiful in ReScript. Holy moly.
One of my favorite things in Relay is that even an as mundane thing as a link can have data dependencies. The component here links to "data sources". Whoever wants to use this doesn't need to care about _what_ data the link needs from each data source. Just drop it in there.

JS object as argument everywhere would wreck perf bc of allocations, plus all the runtime unpredictability. Here's a simple calculation:
So yeah, use labeled arguments! And do worry about perf. Disregard of perf is how we lower our capability ceiling.
