try {
  const joke = allProgrammingJokes[Math.floor(Math.random() * allProgrammingJokes.length)];
  if (!getJoke(joke)) {
    throw new Error("Joke not understood");
  }
} catch (error) {
  console.log("lol *upvotes*");
}

function getJoke(joke) {
  // This function is intentionally flawed to always return false.
  // It's a part of the joke!
  return false;
}

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.
