Question #Javascript folks! If I use destructuring assignment as below, is an actual array allocated for the function's return value, or does the runtime recognize this and optimize it away?

Asking for a friend living in a tight loop.

const [a, b] = foo();

So! Many! Kittens!

(Going to record a demo of the new interactive shell – REPL to some – and multi-page Settings this afternoon, just planning it out now.)

Oh and is that me creating and calling web routes interactively in the REPL on a live server? Why yes, yes it is.

:kitten: Kitten’s interactive shell (REPL) now saves session history scoped to your app so it will still be there when you next serve the same app.

I think I’m done with the REPL feature now.

Going to take a little break, step away from the computer, and make a plan for the next week of work on Kitten and Domain¹.

Upcoming #JavaScript iterator methods:

// Without iterator methods:
const arr = Array.from(myMap.keys())
.filter(k => isPublic(k));

// With iterator methods:
const arr = myMap.keys()
.filter(k => isPublic(k))
.toArray();

(I prefer not to do .filter(isPublic) because isPublic() may gain more parameters in the future.)

Getting Started with Observable Framework 👇🏼

Here is a great resource for getting started with Observable Framework by Allison Horst. Observable Framework is an open-source JS library for creating dashboards. The sequence of videos covers how to set up a project and data loader, customize the dashboard, and deploy it.

Theo on const vs let in #JavaScript:

https://youtu.be/dqmtzHB2zTM (32 min).

It's a long video, and he's basically only reacting to and commenting on Let me be https://www.epicweb.dev/talks/let-me-be (12 min) by Ryan Florence.

Theo's main point is that const doesn't mean "this value will never change" (since objects and arrays can obviously still be mutated), but that let means "pay attention, this value will be reassigned further down", and I totally agree.

#const #let
