I always forget that objects can be accessed like arrays in JS and used the somewhat redundant Object.keys(pairs)[x] approach instead of pairs[x]

very cool!!!

Elegant. I've learned so many simple but non-obvious design patterns just in a few weeks of coding exercises on here. Thanks for this one!

Damn I thought the matches key was invalid. 😅 Awesome job!

Why is this rated so highly? This solution modifies input to then return a result, which is awful.

Great job refactoring the line of code into one line

same :)

What he is saying is that the function is mutating the original signature array.
You should make a copy of the signature array. You can do that with const aryintSignature_Copy = [...signature];

Wow, such a clever sollution!
I was breaking my head on excluding those 'edge cases' (n =< signature.length) from the loop.

What would be a good practice to eliminate overcomplification?
Is it to write all possible inputs and outputs in 1 overview to spot the most efficient pattern?

But thnx, this was a great lesson.

nice

for sake of learning, why is using slice not a good practice?
