📋 Description of content that is out-of-date or incorrect

• The difference in behavior between memos and derived signals isn't clear enough, which makes it harder to understand when to use memos instead of derived signals

• The side effect example doesn't cause an infinite loop but the sentence right above and below it talks about infinite loops which is a little confusing. The reader might think that the example code does cause an infinite loop even though it doesn't

• The "Keep logic in memos" example doesn't behave the way it says, the memo will rerun every time count() changes
