I'm still as lost as I was before watching. I guess I need a break for my brain to work again...

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

@sureshmg6786 4 года назад

@@TheCodeholic you mean like accumulator1, accumulator 2?

@TheCodeholic 4 года назад

@@sureshmg6786 No, I mean accumulator, item. The first argument of the reduce's callback is accumulator and second argument is array element. developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/reduce

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
