Discussion on: I wrote a crawler for the first time.

Tip, there's no point in in using a try-catch if you're just going to re-throw the error. In other words, this

try {
  doStuff()
} catch (err) {
  throw err
}

is functionally identical to

doStuff()

Tip, if you’re going to give unsolicited advice on someone’s code in a blog post, at least comment about the core of the post. Like, “hey great job! This is something you could do instead:” or “hey this blog sucked and here’s why:”

I see your account is brand new, so I’m hoping to help educate you on a little bit of etiquette in regards to constructive criticism. Hope that helps!

Well seeing as you asked, here's why this blog sucks:

A web crawler is not a technically challenging task. As we can see from the post above, it's just a combination of basic web programming steps such as making HTTP requests and HTML parsing.

That it took someone whose core competency is front-end development 9 years to tackle something so straightforward is fairly risible. I don't see how you can claim to be a "senior-ish" front-end engineer yet be apparently ignorant of core concepts such as error-handling and asynchronous programming.

Hope this helps!
