Implementing Promise.race polyfill | Javascript | AwwFrontend
Thanks for your tutorial. Finally someone offering something beyond a PowerPoint demo on this topic. I have a question: I assume that CommonJS and Node operate on the backend, but I believe that at some point a CJS module will make its contribution on the frontend, so how could I invoke the work of a module in the html?
very nice tutorial. well done
This helped me a lot at work today. Thanks
the best video ever thank you so much!
This will not actually cancel it. It will still go inside .then. Cancellable promises do not exist. You can use bluebird-promise for cancel function for that but they will also break if you are using a library using native promises
Thank you
This is helpful, it was easy to understand.Thanks!
Thank youu
Thanks Lavkush; Please make some more videos.
Woww Thanks !!
how to add it on “recommended”?
Excellent information. Really appreciate your effort. But please do improve your microphone quality, audio was way too low.
your voice so small, im about can't hear much
good video. thanks mate
Thank you for the video! Very clear
I love that you explain a lot of concepts which are usually overlooked. Keep up the good work!
Thanks for the help! I didn't realise it was so easy to use.
Did you actually listen to the audio on this before you uploaded it?
Nope. do you have some feedback for me?

Can you please provide Github link for this
thank you very much for detailed explanation <3
exellent thanks!!
Hi Vikas, this looks great 🙌 I had few questions: 1) What framework are you using to launch browser instance? 2) Where do you store the auth state and how do you share that between different docker images? 3) If you are taking median of five reports to generate core web-vitals, then how do you decide out of those 5 HTML reports which one to publish at s3? Thanks !
1. Using puppeteer to launch browser and login, before auditing the given url, documentation here - github.com/GoogleChrome/lighthouse/blob/main/docs/puppeteer.md 2. In the config file, each URL has its own credentials so lighthouse can audit given URL independently. But we do we pick which URL to be audited in which docker? Lets assume we have 10 URLs in the config, and we want to audit 5 URLs parallel then we also pass the index value to docker while running it(docker run lighthouse-ci --shard=1/5) so now index=1 will pick first 2 URLs and so on. 3. Nice Question, so we don't pick each web-vital based on the median value instead we pick the compete JSON/HTML report based on the median value of the `interactive` web-vital.
I'd say it's pretty good video, but kind of complicated implementation. I believe it can be written more easily. es6 is optional, but it also put methods in prototype.
Correction: instead of if(index === promiseArray.length - 1) , we should maintain a count counter, and keep +1 to it as we receive the response. Then we should check if count === promiseArray.length
Please also corret this in you r medium article
Great explanation!

What’s the difference between race and any? 🤔
The key difference between race and any is -Promise.race is settled as soon as any of the promises you feed it settle whereas Promise.any is settled as soon as any of the promises you feed it is fulfilled or they are all rejected
Thanks for the video. ❤
