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.

Support

at least ES2015

Install

yarn add @ag1/return_switch

Usage

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

Test

yarn test
