ts-match
A TypeScript implementation of Rust's match control flow operator
Basic usage
from example.ts:
import {match} from './mod.ts';
function doubleOddHalfEven (n: number): number {
const result = match(n, [
[n => n % 2 === 0, n => n / 2],
], n => n * 2);
return result;
}
console.log(doubleOddHalfEven(2)); //=> 1
console.log(doubleOddHalfEven(1)); //=> 2
console.log(doubleOddHalfEven(12)); //=> 6
console.log(doubleOddHalfEven(5)); //=> 10
console.log(doubleOddHalfEven(3)); //=> 6
