I would just hate if some regulator mandated browser engine choice but forgot about the add-to-homescreen UX.

To be fair, that’s something a linter usually catches.
But what’s the status of “sideEffects: false" in package.json or a similar mechanism?

Yes, that with the rational numbers resonates more with me. It all depends on your choice of equality. The refactored program should be equivalent to the previous one, if equal means that it produces all the same outputs for the same inputs.

haha, I feel we’re straining the analogy. all I can say with certainty is that if you have a monoid, applying the identity element (e.g. multiplying by 1) does the same thing as the “nop” assembly instruction: nothing.

Or as the imperative programmers say: a noop.

More powerful browser on iOS would be nice. But what’s holding PWAs back is that nobody knows how to install them on iOS.

You’re welcome! With all the abstractions it can be hard to see the forest for the trees.

Ah yeah, sounds you need to do myString || null somewhere. Either before sending to the GraphQL server or when setting the useState. And if it’s then uncontrolled you can do value={myString || “”} to do the reverse.

Ah, un/controlled the React concept. But warnings from what, a linter? Or a TypeScript error? In TypeScript, null and undefined are not the same thing, so you’d need useState<string | null>(null);

oh, I never got that deep into GraphQl. is un/controlled a GtaphQL concept? like here? stackoverflow.com/questions/76...
GraphQL field level authorization and nullability
We've implemented field level authorization in the type resolvers of our server, where a field is only returned with a value if the user has access to it, otherwise "null" is returned (with

The GraphQL server doesn’t accept it and you cannot change the server?
Or if you can change the server why not make the field optional and use undefined instead of empty string?

Oh, you are right! But that’s unusual. Perhaps because the event queue is already quite full or something like that?

In the React ecosystem good pattern change into bad one every other year ;-)
But what is your team struggling with? Initial page load speed? Development/iteration speed? Bugs? Regarding global state management, or..?
