What is Satisfies Keyword?
The satisfies keyword in TypeScript is used to ensure that a value conforms to a specific type without explicitly declaring that type. This is particularly useful when you want to check that an object's structure matches a type definition but still allow TypeScript to infer a more specific type for the object's properties. It validates the shape of the value against the specified type, and if valid it retains the initial type information.
