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) =

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 version x.

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 course this assumes the lambda is pure, but in the kind

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; const map = (list, fn) => {

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 hypothetical, so it's not like they've proven gravity fr

`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.
