Node v than 8.x should be enabled

ahhh right...thanks !

Don't use chained methods when debugging your code, use simple loops, see why your code fails, and only then try to use them.

Desperately missing tests with numbers that aren't integers.

this two are very much alike, but mine

• has to behave a certain way when passed 0 or 1 number arguments,
• still returns a useful result if some arguments are not numbers.

Duplicate of http://www.codewars.com/kata/sum-of-all-arguments-1

This statement If 1 number is provided as an argument that number must be returned is redundant.

It adds nothing to the Kata requirement, which already says It has to return the sum of all numbers passed as arguments (however many are provided)

.

Are you sure this isn't a duplicate?

Initial code does not match the requirement.

Fully agree.

Unfortunately, editing the kata doesn't seem to work, so nothing to be done about it.

i think it should be "fib" throughout the kata description, not "fin" sometimes.
