I'm still baffled why you don't see JavaScript is fast, but how page rendered is the issue.
I’m baffled you don’t believe in benchmarks, but, uh.
Speaking about benchmark.
Node vs Lua shows Node faster than Lua. https://benchmarksgame-team.pages.debian.net/benchmarksgame/...
Node vs C, only 4 to 5 times slower. https://benchmarksgame-team.pages.debian.net/benchmarksgame/...
Looking at its root, it is not too bad as a JIT compiled language.
“Only” 5 times slower? Imagine if every website that takes 10 seconds to load instead took 2 seconds…
You know that CPU-bound performance would take a really small fragment of those straw man 10 seconds loading a page, right?
If you think 10 seconds is a strawman, clearly you haven’t used sites like GitHub on a cheap device.
life finds a way ?
