In Sort array of objects usersSortedByScoreDesc still returns asc i believe?

But great reference all together!

[Victor Hazbun]

Fixed! Thanks again!

[Dennis Keirsgieter]

Did you also include the fix? The result is still the same for me even after a hard refresh!

[Victor Hazbun]

Please refresh again.

Worked for you now?

[Dennis Keirsgieter]

Yes it works now! Altough the json.stringify was actually nice to make it more readable :)

[Victor Hazbun]

I used it for debugging purposes, but now you give me a good idea 😁 - I will put it back everywhere later.

Broken chrome tab after too many embed code editor :) It would be better if it had been placed less opts.

[Victor Hazbun]

I will try to split my blog posts, i.e. Part 1, Part 2, etc. Since the embed code editor gives the reader the ability to play with the code. 😅

You bet, I will continue adding more of this for you.
