Thanks for your content. It helped me a lot. I encountered some of those questions in an interview and wanted to know how you would answer them: - How can we unstuck the event loop when an infinite loop occurs? - React has an automatic batching feature. What is the limit of the batch?

HI,Your video is so helpful and I have discovered your channel。❤By the way,I can use React or Vue to build website,and use nodeJS or Nest to build web Service。Then,I don't know how to improve my skills of frontend。looking forward your reply。

[@chandang754]

can you please provide the web application name you are using to demonstrate?

[@pradeep7573]

Can you guys provide information about microfrontend architecture with some simple collaboration using react header, angular footer

[@therealseniordev]

Is on our roadmap @pradeeep

[@Tassaczek]

I work with MFE (single-spa) and I do not fully agree with the answer. Reasons to have it: After a company merge (or similar situations), your codebase may be written in different frameworks, but you need to merge them. We have a React app as one of the tabs in a Vue app (as a parcel). You work on 2 or more apps that share components, libraries, etc., and for any reason, you do not want to have them as npm packages. I would argue that splitting a "big" codebase is not a reason for having MFE. You can easily create module folders in a monolith (just as you would split into other apps). It provides the same freedom to work on separate parts of the app without the headache of putting the MFE together. In my opinion, MFE should be the last resort.

[@therealseniordev]

yes MFE should be the last resort, monorepo is a great option indeed

[@DheerajSharma-hw6qm]

In case of cookies what happen when client is a server only making request o another sever?

[@therealseniordev]

In very general terms, there are no cookies in a server to server request - no Cookie Header will be sent. The cookie header is sent under the hood by the browser if cookies are present.

[@huangjian7749]

i can’t understand because you have the strong accent 😂😂😂😂😂😂😂😂

[@48265868]

If a "Senior developer" asked me "If you are setting up a new fortend application, what are some optimizations you would put in place in order to make it more performant" I would properly just walk out the door since that question is so bad and does not even make any sense to ask like that. Answer is even worse. Saying React in the same sentence as Performance make even less sense xD

[@therealseniordev]

You might argue the question is a bit open ended, yes, but very legit. This feels more like a complaint rather than "constructive critique". If you take time to comment make sure you add to the conversation rather than subtract. This kind of attitude is toxic and what we stand against at theSeniorDev.com. If you don't like the video, feel free to watch other stuff. Maybe record a better one yourself. Cheers to creating instead of hating, Dragos

[@DanZ-fq2qs]

Nice series except that webpack is not relevant any more.

[@therealseniordev]

Hey @DanZ although webpack might not be as used as before(still 80% usage according to the state of JS survey 2022) is still one of the best tools for learning - Vite and other bundlers use the same patterns, but under the hood with "zero config".

[@DanZ-fq2qs]

this dude is too prepared, and is not being challenged at the answers, make this feel less like an interview

[@therealseniordev]

Although we try to make it as realistic as possible we also try to make the answers complete so viewers can see what a good answer will look like. We are preparing a more real life series where we will mimic a real interviewer (more follow up questions, more interruptions, more aggressive tone, etc)

[@pradeep7573]

As long as very useful information is shared , being prepared or not doesn't matter
