good
Thank you very much for taking the time to answer a noob's question.
That's not an array. Try
console.log(invert([1, 2, 3, -4]));
This is what I passed: console.log(invert(1, 2, 3, -4));
are you sure you're passing in an array to the function?
Why does this solution give me the following error in Visual Studio?
"Uncaught TypeError: array.map is not a function"
You can. Just do it:)
Is there a reason you can't just do return array.map(x => x * -1)? I mean, if you're multiplying everything by -1 it returns everything's inverse...
This was my solution as well, except I have added one more check to see if
array.length === 0
. But now that I see this, I realise that additional check was redundant. Nice :)Use spoiler flag!
