I've recently come across the satisfies operator in TypeScript and I'm trying to understand how it differs from regular type assertions. Both seem to provide a way to work with types, but I'm not clear on when to use one over the other.
- How does the satisfies operator enhance type safety compared to type assertions?
- What kind of errors can be caught using satisfies that might be missed with type assertions?
- When should I prefer using satisfies over type assertions and vice versa?
// Satisfiesinterface User1 { username: string; passcode: number;}const user1 = { username: "joe", passcode: 2076, email: "user1@test.com"} satisfies User1;// Type Assertioninterface User2 { username: string; passcode: number;}const user2 = { username: "doe", passcode: 3000, email: "user2@test.com"} as Person;
