I feel like in general people underestimate just how fast computers are. Crazy to hear about libraries that choke on a couple thousand points when compared to https://hackernoon.com/drawing-2-7-billion-points-in-10s-ecc... (for instance)



completely agree.

additionally, it's hard to overstate how impressive modern javascript JITs are, as well as GPUs.

every time i visit a web page that downloads 2MB of js and spins up my CPU fan, i feel ashamed that this is the industry (webdev) where i make my living.

at least with uPlot i show that all this waste is not necessary.


The problem with large websites is that there's a dozen layers of abstractions leading to large and inefficient code. But when it comes to just raw speed (iterating over a huge array of numbers in a tight loop, like drawing this chart), then it's blazing fast especially with JIT. That's specifically where a lot of people underestimate JS. I've seen a lot of people do things in the backend when they can just send all the data and do all the filtering/sorting locally leading to much faster UX.


Interesting read indeed. Too bad this was posted to Hackernoon, had a hard time reading it due to the header bar constantly dropping down into the text I was reading. So frustrating!


Yeah. This is still tens of thousands of instructions per point.
