Function match

match creates a pattern matching expression.

• Use .with(pattern, handler) to pattern match on the input.
• Use .exhaustive() or .otherwise(() => defaultValue) to end the expression and get the result.

Read the documentation for match on GitHub

Example

declare let input: "A" | "B";

 return match(input)
   .with("A", () => "It's an A!")
   .with("B", () => "It's a B!")
   .exhaustive();
