I unfortunately recommended a Firefox addon somewhere. Maybe it (Disable JavaScript) or some versions of it got hacked/backdoored because the repository just up and poofed itself. Luckily, Firefox isn’t that popular.

Addon files are usually zips and CRX Viewer is good for corner peeking. I look around corners thrice, occasionally, sometimes, maybe?

I’ve just learned something the hard way. There’s stuff out there that spins console.clear() and debugger in infinite loops. I don’t know why that’s a thing but I like to call it: clear console log debugger abuse.

In Chrome/Chromium limit debuggers and logs. In Firefox, enable log persistence/timestamps and control breakpoints manually.

My brain was picked apart the other day. Virtual scrolling is, in a handwavy sense, pagination with (semi) automatic navigation. Touché.

Infinite scrolling is unusual. Most implementations are “almost infinite” to avoid excessive DOM length (memory).

• Infinite scrolling: Limits content to an arbitrarily large amount to avoid exhausting memory.

• Virtual scrolling: Unload everything except the visible viewport + a top and bottom offset. Pad the rest.

Virtual scrolling is infinite, but breaks auxiliary actions ( CTRL + F ) because what’s on the screen is the content.

document.addEventListener("scroll", function() {
  console.log(document.querySelectorAll('*').length)
});

The most popular library appears to be https://infinite-scroll.com.
