Having troubles working with filter etc on arrays?
I’m not that far into it (err…number 4) but you should really check Array Cardio Day (n 4), where Wes Bos works through arrays with various methods (functions?) like reduce(), filter(), etc.
Plus nice tips - such as
console.table() and intro to ES6 stuff. Like the fat arrow.
[EDIT] If you can’t be bothered or would like to check out the code directly, visit Wes Bos’ repo.
