Well, I definitely need to learn the .reduce method — thanks for the idea!

| defaults to the next value if the previous one is falsy, || compares if either comparison is true. 0 | 'String' resolves in String, 1 > 0 || -1 > 3 resolves in true.

O(n²)

| is technically the bitwise OR operator, while || is the logical OR. The first one works with the binary representation of the values being compared (coerced to numbers), while the second one works directly with the values being compared.

You just taught me how to use reduce, thank you!

Sorry, can someone explain if there is a difference between | and ||?

если код в функции реализован в одну строку то можно обоитись без скобок и return

I was totally over thinking this.. thought you had to pass the args into the function so it wouldn't let me pass any tests.

Short n clear!

I think this solution is not what a beginner would provide

Not a kata issue! Your code has incorrect spacing count when encountered character is a space

Well damn, I thought common sense would serve me well in programming!

neat and concise

great ! i hadn't thought of it

yeah but the problem was too
