can you create a new file (called Ada-11.js)? that way there's no way that multiple solutions conflict with each other.

also, it is considered a best practice (and thus strongly encouraged) to use unit tests to validate solutions: that way you can clearly see that a particular solution is passing (or failing) the tests quickly by executing it. We also have set up CI to automatically run that every time!

you can see how to do that in L10-16 in this file or

data-structures-and-algorithms/JavaScript/chapter01/p01_is_unique/avc278.js
