It's called a spread operator, you can use it to define "the rest" of arguments, like (a, b, ...rest) and that'll be an array of the additional arguments. You can call this as myFunc(a, b, c, d) and the rest argument will contain [c, d]. I hope this makes sense. :)

Could you explain what is doing ...names?

cool

short and sweet

There is no point in this kata. Literally everything is hot garbage. ;-)

Seems like the point of the challenge was to implement JSON.stringify(), no?

Thank you.

Congrats man, elegant code.

To prevent cheating a new test spec disallows "new" anywhere in the nouveau function source.

Lack of test cases.

It's a nice one, just didn't really understand the purpose of "code quick, as fast as you can."

Main fn doesn't have any argument like (arr) or (n).

Why should the coder have to copy paste the houses from the description to solve the Kata?

Missing tests.

More information would be nice, like some tests, which provide something about how data will be passed.
