Thing with JS pipes: if they had reference to result of last operation (so-called pipe placeholder), it could be useful outside of pipes as well.
a |> # * 2
same time
a ? # : b

and the inverse multiplexor? operator a -< selector

operators will be more punctuation marks

If I ever do a new language, there will be this:
a,b,c >- a,b -> a+b
meaning reduce a,b,c by a,b -> a+b reducer

I wonder isn't that part confusing for F# programmers:
|>, ||> and |||> call the function down pipeline with 1,2 or 3 arguments from input.
But Fira converts that to ▷, |▷ and ||▷ - which loses number of bars indicating number of arguments.
Ternary operator should really have short binary form.
a > b ? a = b;

Clever use of reflecting state in attributes
Quote Tweet
When the component goes to status "connecting" it gets the attribute:
status="connecting"
I then use the :host() selector to show or hide certain parts inside the component based on this attribute:
:host([status="connecting"]) .connecting-container {
display: block
}

Chrome supports import-maps. Meaning it's possible to run modules both in node/browser without any tooling. Nice.

Wow, WeakRefs / FinalizationRegistry are just fine.
Testable via global.gc() fairly easily.
A point on off-threading stuff to web-workers.
Make sure amount of calculation is going to outweigh creating an isolated heap and garbage collector for maintaining a thread.

It's egoistical from nodejs and npm side to call `modules` `node_modules`.
There can really be things having nothing to do with node: CSS, SVG, fonts, browser libs, deno, etc.
It also makes import path look ugly and fragile:
import htm from './node_modules/htm/dist/htm.module.js'

Would be nice if github besides security bots had optimization bots - making PRs with memory leak fixes, perf/size improvements etc.

Curious observation:
Hindus use low order in donations as recurrent flag. Eg. donation of $100 means “that’s it”, but $101 means “let’s continue”

Should admit I was wrong about esbuild.
1. it doesn't generate the most minimal source, still have to apply terser
2. it deliberately wastes code formatting github.com/evanw/esbuild/
The question is - it does fast what? Generates suboptimal code? I don't mind spending extra 60ms

Functional subparsers provide nice leverage to corner performance. But the main formula is the flatter the better.

Website ads is cancer.
TIL: performance intuition in JS boils down to total number of operations (compared to code size in code golfing).
One possible way to measure is to count number of function calls, esp. lookups.

Maybe will come up with that sort of structure in subscript, ':' is operator afterall.

Objects are ordered, but arrays are not keyed.
That could be useful: [a:1, b:2, c:3]
