Array.findLast() does not seem to be available

[lehni]

Four months ago, Array.findLast() was added to the polyfill-library:

https://github.com/Financial-Times/polyfill-library/tree/master/polyfills/Array/prototype/findLast

But in the URL builder, it is nowhere to be found:

https://polyfill.io/v3/url-builder/

And when I fetch the polyfill.js file on a browser that does not support the function, e.g. Firefox v103, I don't find its definition in the returned polyfill:

https://polyfill.io/v3/polyfill.js?features=all

What am I missing?

We have not updated the polyfill-library version used in polyfill.io, this is why you have not been able to get a polyfill for this feature

Thanks for clarifying. May I ask why it hasn't been updated?

Same for findLastIndex - this was added in JakeChampion/polyfill-library#1230 more than 7 months ago but is not available. Please update polyfill? Thank you!

We ended up self-hosting the library on an AWS lambda… polyfill.io is heavily lagging by now.

I'll be updating it in a few weeks, it's a breaking change though, requires more work than you may realise

@JakeChampion: Looking forward! And, thank you for polyfill!

Any idea where I can find self host instructions?
