This is for a client application that is storing a bunch of plain text in a specific format, where the parsing would happen on a separate worker. If you have any advice for how to make faster JS or for how to learn HTML/CSS/JS interop with those things I’d appreciate it. Otherwise it’s not very helpful to just tell someone “JS is not for performance! No!”. As much as people dunk on JS, you CAN write performant code in it. Like there’s been some decades of work put into making it run faster or be able to make games or something in it...
