Document-api Memes

JavaScript really said "booleans? never heard of her" and decided that "on" and "off" are perfectly valid boolean values. Because why use true or false like a normal language when you can just... use strings? The document.designMode property is the perfect example of JS's commitment to making type safety engineers cry themselves to sleep. Other languages have strict typing and sensible boolean values. JavaScript has vibes and string literals pretending to be booleans. This is fine.
