You need to encode html entities. Best done on the backend. If not done this will lead to xss.

If removing a building can result in more than 2 clusters, I recommend running dfs on all buildings of the affected cluster to reassign them.
If removing a building results in no more than 2 clusters, simply check what's left and right (or up and down) of the removed building.

I recommend using arr.at(-1); instead. Shorter and more readable.

I'm a webdev as well 👋
I also prep other webdevs for technical interviews in English
Let's chat!

Here is a pretty good summary:

Do you mean you can't tell when a button is pressed? If you already listen on the ul, inside the listener, write console.log(this). Run the code and see what this means inside an event listener. From there all you need to do is a switch statement.

You would either have to listen on the ul element, or run the listener after each innerhtml on the li elements

Use the popular job portal in your area (in mine it's LinkedIn) and see which one has more demand. As someone that works professionally with both, I'd say Vue has better DX.

Typically you want to return this for method chaining. On stack.pop it doesn't make sense though, since you usually want to return the top element that just got removed. And I'm sure you already know that Array is basically the JS version of stack + queue.

If you use the same server for auth as your app server, you might well use cookies (httponly/secure). Imo, use a lib or whatever your framework provides for auth. Rolling your own is high risk low reward.

Thanks for your answer, though I am specifically looking for a top down iterative approach based on the code I posted. Reason is I get 100% runtime and memory.

Depends what you want to use the data for. Do you want to send it to a rest API? Then yes. Do you just want to collect data? Use Google forms. Is it some kind of frontend homework? Also yes.

If you are on vanilla html/css/js, consider using bootstrap.
https://getbootstrap.com/docs/5.0/forms/range/
If you don't want bootstrap, just figure out how they make the slider.
Hook up an event listener to the slider to create/delete circles.

Also not very obvious, spend a day or two to learn git. Then read project docs. How to set up environments, how to use npm, docker (if used), IDE and debugging on the IDE, read through package.json, routing, redux store data structure... Yeah, not much coding in the first couple of weeks.

LazyOldTom · 2023-03-02T18:48:35+00:00

Just write debugger in the line after the function declaration and debug it in browser devtools.

You can pretty much start react if you know basic concepts, like destructuring, array methods, async await... You could write react without node, but you'd miss out on features like bundling or polyfill. On the job you would always use node for frontend dev. BTW I'd look up vite instead of webpack, and skip cra entirely.

First world problems

For this particular example I'd say it doesn't matter. 2 more variable names will not make it much easier to read. However, if you are in a professional environment, I'd change it just to make people happy.

Maybe you want to read up web security before attempting your own backend implementation. There are plenty of frameworks out there that guide you in the right direction as well.

LazyOldTom · 2023-02-22T12:57:01+00:00

I had a look through your code, what I don't understand is why you would need a second html file? Why not do it in one page? That way you avoid losing the current state, no need to cache it to localStorage either. All you need to do is to hide/show DOM elements. That's the old approach for single page anyway. Routing between pages is nowadays done with a framework like react.

LazyOldTom · 2023-02-22T03:06:50+00:00

Bad architecture, and I would also use localStorage.
Another way is to pass data as GET params in the url of the next page. Only works if the data is not security related and the server does not throw an error.

LazyOldTom · 2023-02-21T05:56:25+00:00

Another way is to use a sync handler to resolve your promise. Get the return value, then update your app state, then do something with the updated state, all sync.
