Need Advice Regarding JavaScript

Taking notes isn't bad - it is just not the best way to learn to code (arguably to learn any skill). If you find notes do help you, after the lecture/video/session, summarize what you have learned from memory in your notes. This will help the info stick and provide an easy place to look for future reference if you ever end up referencing your notes.

Argument of type 'number | undefined' is not assignable to parameter of type 'number'.

I learn something new every day! Thanks. While reading the documentation, I also learned that combining || and ?? in a series of checks will not work without parenthesis. This is something to keep in mind as I frequently do this too.

I have not used ?? in code before, I have used || a ton.

Argument of type 'number | undefined' is not assignable to parameter of type 'number'.

@jochemm I was going to suggest using a logical OR like so:

 const onTimeUpdate = () => {
    setCurrentTime(() => convertToMinuteSeconds(videoRef.current?.currentTime || 0))
  }

 const onTimeUpdate = () => {
    setCurrentTime(() => convertToMinuteSeconds(videoRef.current?.currentTime || 0))
  }

Do you think the ?? operator better or about the same as || in situations like these? Given, of course, that a 0 will fall through to default as 0 in this case.
