Your career will be derailed for a decade if you go this route
My senior dev colleague recommended me this book saying if I want to become a good software engineer, this book is a must. I heard about it from others as well.

These numbers are really embarrassing for a programming language.
Even a 10x improvement is still embarrassing.
10 requests per second?
A typical Rails app will serve up to 1.5 requests per second per vCPU. With tuning plus an optimized app, that can be up to about 5 requests per/sec/vCPU.
So these days, vertical scaling can buy you 75-250 requests per/sec for 350 a month… not bad. ~5-10x better than Heroku.

This kind of bullshit is very common in code reviews which is how you can tell code reviews do bat shit to improve quality
The most common needless use of `let` I see:
Setting an initial value, followed by mutations.
This is hard to read because it requires the reader to hold the initial value in their head while reading, and monitor any mutations along the way.
Solution: Call a function instead.

Finder, the default file explorer in macOS, takes several seconds to load a directory with thousands of pictures and movies.
The file explorer is most people's most direct (visceral?) experience with computers, and it's very slow when it has to deal with a few thousand items.
This application is comically unresponsive, making thousands of Windows API calls opening files and registry keys every time you change directories resulting in changing a directory taking 1.5 to 2 seconds on my i9 13900H machine.
