# Simple Pattern Matching

For complex logic sometime switch is not enough. There's a pattern matching proposal but it's not ready yet.

https://github.com/tc39/proposal-pattern-matching

## Getting Started

```sh

npm i @eatsjobs/ts-pattern-matching

```

## Usage

```typescript

  import type { Predicate, Handler } from "@eatsjobs/ts-pattern-matching";

  import match from "@eatsjobs/ts-pattern-matching";

  type Input = { a: boolean };

  const predicate: Predicate = (input) => {

    return input.a

  };

  const handler: Handler = (input: Input) => {

    return "this will executed if predicate returns true"

  };

  

  const string = match({ a: true })

    .when(predicate, handler)

    .when(..., ...)

    .otherwise(() => "default string") // default handler

    .run();

```
