People use method chaining all the time and don't have any issue with it? It's equivalent to something like: $result = $arr ->column('values') ->merge() ->reduce(fn($carry, $item) …

Of course HN works fine, if it didn't work fine it'd be fixed by now. "Working fine" is an extremely low bar for any site. As a developer you will still want to avoid quirks mode b…

Node supports ES Modules (the import statements you mention) natively now: https://nodejs.org/api/esm.html

=> also comes straight from math learned in school. There it's written → (for function signatures), and (the more rare) ↦ for function definitions.

0.x releases are also major versions according to semver, just pre-stable. So many people were referring to React 0.x releases as "React x" that they just bumped it straight to ver…

Lambdas are constrained by their type. If you see a lambda being passed to, let's say `map`, then (assuming you know the type of `map`) you know the type of the passed lambda. Of c…

Was just pointing out a nice (probably unintentional) pun

The title probably changed. The URL slug still has "comes-to-an-end".

Let's take a look at how we might write a function like `map` the (pure) functional way in a language like JS: const head = ([x, ...xs]) => x; const tail = ([x, ...xs]) => xs; cons…

I'm reminded of this classic sketch: https://www.youtube.com/watch?v=3m5qxZm_JqM

I'm a JS dev that learned Haskell over the past few years. Anything in particular you're curious about? I guess if I were to mention one thing I really miss in Haskell it's having …

"Demanding" anything from a superior is a bit of a no-no in Japan, even if it's something as simple as a phone call.

Not a physicist by any means, but from the article it talks about gravity in the context of the graviton (as one plausible solution to the problem mentioned). Which is still hypoth…

It's a React component for data tables. So it implements (re)loading data, sorting, pivoting, and the other stuff mentioned in this feature list: https://github.com/tannerlinsley/r…

That moniker should probably go to E4X: https://developer.mozilla.org/en-US/docs/Archive/Web/E4X_tut...

`const` variables are actually inferred without widening. So in your example `dir` would be inferred as `"up"`, not `string`. If you use `let` (or `var`) however that would be true…

Agreed! If a conscious decision is being made to value the ability for people to own guns in expense of frequent killings then go for it. But it's usually phrased as "there's nothi…
