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.

Examples

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

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