Agreed. I mostly keep the state in some container components and only use redux if it's really needed. That approach works just fine.

Interesting that this article got upvoted like hell on Reddit, but only gets downvotes here :)

Any reason for that?

IMHO it is a solid list. If you know all the topics mentioned, you are probably able to pickup any framework quite fast and have a good understanding about how JS works.

Not sure if this was made 100% clear in the article (although it's mentioned), but instead of an IIFE you can also use 'let' in the last example:

for (let i = 0; i < 5; i++) {
  setTimeout(function () {
    console.log('index: ' + i);
  }, 1000);

Yeah, I intentionally did the example with a number, because there you have the problem of 0 being falsy.
The `??`-solution would be nice IMHO.

Cool proposal in general, although there are still cases where _.get is somehow nicer:

const num = _.get(foo, 'bar.baz', 1337);


const num = typeof foo?.bar?.baz !== 'undefined' ? foo?.bar?.baz : 1337;

Interesting pattern, but this will probably result in some huge components where everything is plugged together. Would definitly like to see a bigger codebase using this approach.

Sorry, I know it might not be that cool to post a link to a Reddit discussion.

That said, IMHO it's quite useful to understand that even if you're passing​ object like things as arguments into functions, it's still call by value. You're copying a reference in that case.
