Wow the real world example helps alot. Thanks

[@williamjog93]

Thanks for the excellent explanation, using separate methods and then combine them into a new function.

[@Summer9604]

In the last example .map() just felt like another .filter() , good video!

[@TheCodeholic]

Love your comment man,
Just item1 should probably be named as accumulator

[@sureshmg6786]

@@TheCodeholic you mean like accumulator1, accumulator 2?

[@TheCodeholic]

@@sureshmg6786 No, I mean accumulator, item.
The first argument of the reduce's callback is accumulator and second argument is array element.

Ur watch time would increase if u would just zoom in and make it easier for us to see what's going on in the screen. Or people would just stop watching ur vid midway like how I am leaving

[@TheCodeholic]

Thanks for your comment. I am already doing this in my latest videos.

[@alexmercer6585]
