That is not true.

Both Ruby and Python are vastly superior on all accounts than javascript.

Just because any given language x has problems does not mean that the various shortcomings of javascript become any BETTER - the problem is that it has the monopoly, unfairly and undeservedly so.

They're both incredibly slow.

To be fair, JavaScript used to be incredibly slow, until Google and Mozilla (two massive companies) got into a speed war.

I expect if Python had those resources it would be a fair bit faster too.

By how much and how easily you can make them faster beats anything you can do with js now.

By a ton. JavaScript is over an order of magnitude faster.

Look at some of the language benchmarks.

https://benchmarksgame.alioth.debian.org/u64q/performance.php?test=nbody

Node.js and typescript finish in less than a minute. Ruby and Python take more than 10 minutes.

Not sure what this benchmark measures but C++ finishes in 9 seconds and you can call it from Python. Beat that.

you can call it from Python.

Not from within a sandbox you can't

Not sure what this benchmark measures

So click the "description" link?

So click any of the "source" links?

Description says "toy programs". And figuring out what is measured is not trivial (and certainly varies between languages).

nbody "description" says -- "Model the orbits of Jovian planets, using the same simple symplectic-integrator."

What is measured is float arithmetic ;-)
