Search - "flatmaps"

Just spent 30+ hrs on an error that was due to using flatMap instead of map.
I feel stupid!

There was a 1 second delay when loading images on home page with a bunch of hot model babes in a masonry grid
Why? 💧💧
Maybe pagination is fucked. Lets reduce it from 100 per page to 10.
Still same shit.
What do you think why this could be?

(The images im loading are just dummy images from unsplash)
I tried using rxjs. Observables. Flatmaps. Custom array push. Array loop. Change detection to update UI. Chatgpt.
Nothing
Every time i switch tab and come back then theres another second of delay with blank page before content appears
Wtf???
Turns out -- unsplash api was returning me 6K to 8K Fucking images. HEAVY. HEAVY FUCKING IMAGES. and i was apparently displaying 6000x8000 px images, 20 times per page. Thats a lot of fucking pixels! I reduced it with ?w=500 in unsplash api at the end and magically there is no delay now and everything works in an instant.
Fuck off6
