Pattern matching in Cangjie uses the match expression to elegantly deconstruct Option types by checking against explicit None<T> or specific values. It enables safe branching logic to extract and manipulate potentially absent values without crashing the program.

The best way to provide a default value for an Option type in Cangjie is using the null-coalescing operator (??). This operator evaluates the Option and returns its contained value if present, or falls back to a specified default value if it is None.

Yes, you can use if-let conditional destructuring and while-let loop destructuring in Cangjie to safely bind values from an Option type. These methods allow you to execute code blocks only when the Option contains a valid value, ensuring robust null-safe programming.

Cangjie supports the safe navigation operator (?.) to perform safe member access on Option types. This operator safely accesses properties or methods of a potentially absent value, returning None automatically if the original Option is None.

You should use the getOrThrow method when you want to explicitly unwrap an Option<T> and force a program crash or throw an exception if the value is absent. Pattern matching is preferred when you need safe, conditional branching without throwing exceptions.
