hi everyone!I have got some task which I can not really figure out. I would appreciate any help
I have got an array of arrays
[
[ 'STD', 'Standard', '5.5', '7.83', '9.9' ],
[ 'STD', 'Standard', '8.5', '7.83', '9.9' ],
[ 'STD', 'Standard', '9', '7.83', '9.9' ],
[ 'STD', 'Standard', '8.25', '7.83', '9.9' ]
]
I need to loop over them and return something like this -
[
['STD', 'Standard', '31.25', '7.83', '9.9' ]
]
where the 3 element is a sum of all 3 elements of previous arrays
How newcomers are aware of the rules? I guess they don't need to be aware of those automatically detected. But for the rest of the rules, how do they know them?
@benja-M-1 that's a great question - definitely the lintable things they find out about on their own, because they can't merge code that violates these. For the others, we rely on code review to communicate these sorts of things (and in onboarding, everyone is made aware of the existence of the guide, and encouraged to read it)

gitter channels are primarily for specific repos
use irc for more general topics
since this is a style guide, there’s not many things that external contributors can help with. Take a look at https://github.com/airbnb/javascript/labels/pull%20request%20wanted
gitter's better for per-repo questions
hi
and any .bind is the same Function.prototype.bind
so,
bind.apply(f, ...a) is the same as f.bind(...a), but without relying on f having the right 1st bind` property go f
Thank you.
Spent 2 hours just to figure this out
