Ask HN: Is a JIT Necessary for a JavaScript Runtime?

Hello! I am considering eventually writing a Web browser as an educational project.

I’m wondering if a browser with a JavaScript interpreter without just-in-time compilation would be too slow to be actually usable.

I think you could argue that if a site is unbearably slow in a regular interpreter, it’s probably also slow in v8 or another runtime.

I don’t doubt that I could write one... Just wondering if all the time is worth it.

Thanks!
