Return Switch

Control Statement that can return result is cool. It can reduce ugly code. Some other libs have done this but they are too complicated for our need.

at least ES2015

yarn add @ag1/return_switch

import { returnSwitch } from '@ag1/return_switch';

const foo = returnSwitch<string>('foo')([
    ['foo', 'foo'], // matched
    [true, 'bar'],
]);

console.log(foo); // foo

const bar = returnSwitch<string>('bar')([
    ['foo', 'foo'],
    [true, 'bar'], // default
]);

console.log(bar); // bar

const lorem = returnSwitch<string>('lorem')([
    ['foo', 'foo'],
    ['bar', 'bar'],
]); // NO_MATCH, throw error

yarn test
