If you do a type check with None, and there is some value inside (so it is Some, not None), it is IMPOSSIBLE that the .value that you extract underneath is gone. This is an important race-condition that you might run into due to the nature of TS/JS, but by boxing the value with an immutable Option type, you're protected.

Also this prevents people to run into NullReferenceException (or UndefinedRefsExceptions, or whatever is called in this ecosystem) for people that didn't turn strictNullChecks ON.

Deps should be updated when you need some features or bugfixes from the new versions; not just when DependaBot prompts you to do it.

I see value in DependaBot and things like that only to check that your module still passes your CI with upgraded dependencies (and if not, then it's worth looking at the failure, to be prepared for the updgrade in the future).

What does this mean, sorry?

> the edge case collapse the entire system.

If you mean that if it reaches a certain point, the entire system will collapse, it means you don't understand the difficulty adjustment. If it's too expensive to mine, then some miners leave, which makes blocktimes be longer, but not to worry because the consequence of that it just that difficulty will go down, which means that you need less hashrate to mine (and maybe some of those miners that leave will come back because it is profitable again for them). This means that it is essentially impossible for all miners to leave at the same time; some of them stay even if at a loss, and some of them are just hobbyists that can already feed their miners with solar power (so there's really no loss for them in leaving them connected).

But yeah it's a fair point. Sometimes I think I should just write my own lang (a subset of typescript), in the same fashion that Lisette dev has done.

Thanks for raising this kind of things in such a comprehensible way.

Now what I don't understand is that TypeScript, even if it was something to make JavaScript more bearable, didn't fix this! TS is even worse in this regard. And yet no one seems to care in the NodeJS ecosystem.

That's why I created my own Option type package in NPM in case it's useful for anyone: https://www.npmjs.com/package/fp-sdk

In Spain, I take ~600km trips every once in a while. I just need to charge once in the middle of the trip, in a super-charger that is. And the charge is 25min maximum.

Your experience varies is basically opposite from my experience. Your situation is probably influenced, indeed, by the poor choice of EVs you purchased (range is the most important factor for me to buy) and the lack of superchargers around your area.

I'm very happy with Pi myself (running it on a small VPS so that I don't need to do sandboxing shenanigans).
