Me in the interview: "Generally, no, a variable can only be assigned one numeric value at a time. However, Javascript is famous for unpredictable behaviors in variable comparison statements, for instance [] == ![]. There's actually a whole library built around documenting this type of behavior this for comedic value, and other more serious libraries geared towards solving the problem. So it's possible that some obscure variable assignment scenario would result in that line evaluating as true, but it's not something you'd expect to encounter in the real world. This has gotten a lot better with typescript and es2022, but still something you need to watch for a bit."
