Would be nice for the TypeScript template to have proper type annotations: rather than input: any, input: number[] | null would be more accurate.

This is definitely not a good practice. Whenever you see a literal true or false you should always ask yourself if you can get rid of it by analyzing the boolean expression. Most of the time you only need to return the result of the boolean expression, as in this case.

Passing all tests in C++ except for the RandomTests, which throw an "unknown exception". Has anyone else had this problem, or is it just my code?

You don't need ternany operator.

Achievements, as far as I have seen, just means the points that you get from leveling up e.g. from 7 kyu to 6 kyu.
