| Pointer compression saves an average of 40% of memory.

This is really awesome. Can't wait it to be shipped everywhere.

I wonder if this is specific to v8 or could SpiderMonkey and JavascriptCore could benefits from the same optimisation technique.

It's used in other languages too, but how easy it is to apply to another JS engine depends on its implementation.

Nothing v8 exclusive about it though

I believe JVMs were the first to use pointer-compression.

I'm impressed by the amount effort that went into that header svg.

It's pretty cool how it's done via vector graphics AND CSS effects. Also note how it only takes 8kb! However, it doesn't render well in Firefox: it's moved to the right by a lot.

Which version of Firefox are you using? I'm on 71.0 and it looks okay to me. (It's consistent with the IE11 that I have access to.)

I'm using 71.0 on Linux. And actually I misspelled: it's moved to the left not the right. I've deactivated the ad blocker on the site. Screenshot: https://i.imgur.com/ajqXZoI.png

Yeah, sorry about that, it's fixed now.

Thank you!
