    allProgrammingJokes[Math.floor(Math.random() * allProgrammingJokes.length)]

    This might throw array index out of bounds errors.

      ECMAScript spec says Math.random must be less than 1. I was about to stop there, but a thought occurred to me: could the multiply with a float make a number large enough to floor to a different value for large enough values? 🤔

      I imagine it’d have to be a ridiculously large number to amount enough floating point imprecision to matter, if so.
