Weird #JavaScript behavior with Element.remove():

const children = ... // sorted children of container
children.forEach((ch) => ch.remove());
if (1 > 2) {
setTimeout(() => {
for (const child of children) {
container.append(child);
}
}, 0);
} else {
for (const child of children) {
container.append(child);
}
}

The setTimeout branch works, the other not. Anyone? @rauschma would you have an idea?

A shallow explanation: removal needs one round of the event loop. But why?

I made a thing, and documented how to make unfied type mapping for PGLite and PG (and postgres) https://github.com/Ciantic/pg-unified-mapping/tree/main

It is very rocky road! Timestamps, dates are *totally* broken by default, arrays are flaky.

If you ever use PGLite for unit tests you need to unify the mappings so that tests and runtime doesn't differ.

Self-hosted Analytics with Next.js and PostgreSQL

How I built a fully anonymous, privacy-first analytics system for mxd.codes using Next.js API routes and PostgreSQL without any third-party tracking service.

Has anyone had any luck using `Object.create` for reconstituting class instances from the plain data objects that IndexDB gives back to you?

Like, from the docs it feels like I should be able to call `Object.create(MyCoolClass, dataFromIDB)`, but that gives an odd error, complaining about one of the root props in the data object.

The bottom line in this MDN example is basically exactly what I am trying to do, so I assume it might work?
