Unpopular opinion about programming but,
"Uncaught TypeError: Cannot read property 'myUnpopularOpinion' of undefined."
Listen here, smart guy. This joke is about a common error in programming, specifically in JavaScript. When you see "Cannot read property 'something' of undefined", it means you're trying to access a property on something that doesn't exist. It's like trying to open a door that isn't there, which is a classic "you" move. This dude's unpopular opinion is so unpopular that it is undefined. Get it? Good.
