Why Javascript is 100x Faster than Python

If you've been hearing a lot about javascript performing better than Python on the computational side or this is your first time hearing about it. Well in this video we will go into the details of why javascript performance is better than python 90% of the time on different algorithms, problems, and mathematical calculations.

I am learning both at the moment. I am 39 yrs old and do a re-education. Django with a JS library is a pretty powerful combination.

couldn't find the answer for the title "Why Javascript is 100x Faster than Python".. just running some tests

hyperfine can bench multiple commands and show the diference between them, like `hyperfine 'command 1' 'command 2' 'command 3'`. you should've used it that way.

I like your benchmark type of videos. pls make benchmark comparison about popular server frameworks - laravel, django, exress, fastfy,

[joshgoebel]

This is hardly fair (simple loops). Your using an iterator on Python and just a plain number on JS. This is comparing apples to oranges.

I’d be interested to see the results with bun or deno. Not sure if it would make any difference for the demonstrated applications

[maxwelljohnson]

cringe clickbait, i say as im a node TS dev -that actually understands python

[monsieuralexandergulbu]

It's not fair to first show the slow vs fast and then switch..
If you're using the best performance implementation of JavaScript, then why you're not using the best performance implementation of python from the start? (pypy/cython/numba and not cpython as your showed)

[diegocascavita]

That's the benchmark that i was waiting thanks u !

[ThankYouESM]

I'm trying to code a basic enough Python -To-JavaScript for generating 3D graphics mainly for creating smartphone games.

Python with numba, pypy, numpy, ... is fast.

Have fun using JavaScript while coding a self driving car algorithm. Hope you get the point.

JAVASCRIPT CANT BE EXECUTED FROM THE GPU!!! HOW CAN JS BE FASTER THAN PYTHON???!!
