Js type coercion always makes uncomfortable. Rather just do it explicitly where possible.

man idk, one sentence solutions look cool and smart from distance but code readability is also very important. just saying

nice

While this code does modifes the input directly, it is still a very clever way of solving the problem. I was scratching my head and came up with a solution with if and while but this is really good.

Clever!

non an error?

What would the expected return value be if the input was null?

it does not works with null input.

it works basically like a Fibonacci, but summing the last 3 (instead of 2) numbers of the sequence to generate the next.

• you're right, but depending on the requirments of the kata this is not a valid.

welcome to js

lmao nice

when you return you don't need to add the break couse you already breaking the code
