Answer 1

that's quite easy as excuse ;P

however, I'm agree to help you once again... but it could be the last time if such "mistake" happen again ^^

const addAll = a => a.reduce((a,v) => a+(Array.isArray(v) ? addAll(v)
: v), 0);

Answer 2

why would I help you again?

you've been unfair by removing the best answer mark from my last helpful answer about 7-8 hours after setting it, and you even not answer to my question asking why you did so ^^

Answer 3

Answer 5

Answer 6

visph but please how do you approach the problems? How do you solve them? I keep trying and I spend hours to no avail

Answer 7

visph yes I got it. I meant that how do you approach problems on recursion?

Answer 8

visph aha. Thank you. I'll keep solving more questions on them 😊 😊 😊 😊

Answer 9

if item is array, add addAll(item), else add item... for each items (reduce)

Answer 10

by considering the problem... and applying the solution wich seems to fit ^^

there's no generic rule... (as far as I know)

sometimes it's harder, and could require multiple try and fail... but by solving such problem, the logic come more easily by the time and the practice ;P

Answer 11

visph please after answering this, how do you approach problems on recursion? How do you solve them? What strategy do you use please?
