Great Explanation. Learnt loads of things that I dont find in documentation,
Found a small bug for reduce on accessing property before initalization
Fix:

const { evenCount, oddCount } = arr.reduce((counts, current)=>{
if(current % 2 == 0){
let evenCount = counts.evenCount + 1
return { ...counts, evenCount };
}else{
let oddCount = counts.oddCount + 1
return { ...counts, oddCount };
}
}, { evenCount: 0, oddCount: 0});

I'm going to use the most used comment: "this channel is underrated". I was making a TS module, had an issue, found your channel in youtube and now I'm watching all playlists one by one before I continue.
