The article is about how JWT agrees with independent Hubble telescope measurements. Both disagree with a 3rd measurement that theoretically should be in agreement. Therefore, the theory is obviously wrong/incomplete in a measurable way.
Try using `run` in the return of a React (or similar) component and you'll never go back ;)
There is always a balance here. I'm not saying to never extract a named function, and there is certainly good reason to do that, especially if the function is called elsewhere or is quite complex.
But, in many cases, the inline logic is more readable because it's right there, and the function really doesn't need a name.
I will once more agree with the reasoning on the high level, but:
From my experience working in big react+ts codebases devs are nesting components and logic way to much, resulting in unmaintainable messes that neeed hours to refactor. This kind of utility enhances this mental model of nesting stuff instead of extracting. I am not suggesting the run utility will break the world, and maybe there are quite a lot legit usecases. But it is the equivalent (exaggerating a bit here) of giving every untrained person a bazooka. They're lack of proper use will cause caos

Totally agreed! I wish JS had if expressions (maybe in the future?). It doesn't seem like such a huge change if it were rolled out slowly like other new syntax features but maybe I have no idea what I'm talking about.
Hopefully things like `run` can help move the needle on this. I like it because it feels more FP and intentional than IIFE's everywhere.
Yes, I do think the extra parens are less readable.
Its not about number of characters, its about reasoning that the inline function that you just wrapped in parens is then called later, potentially after many lines. At least with `run` it's immediately clear based on the name that you are running the function.
Completely agreed, and I use this if-based early return syntax frequently! That being said, I like using `if` and `else if` and `else`, but maybe that's just me! I don't think there's a substantial difference in readability or utility.
