#### Note: It works with `env NODE_ENV=development`

Examples:

### Simple

```javascript

const t = require("dtypecheck");

const {expect} = require("chai");

const fn = t(

  number => `${number}`,

  number => expect(number).a(`number`),

  string => expect(string).a(`string`)

);

fn(1) // Good

fn([1, 2]) // Bad

```

### Async

```javascript

const t = require("dtypecheck");

const {expect} = require("chai");

const fn = t(

  async (number) => `${number}`,

  async (number) => expect(number).a(`number`),

  async (string) => expect(string).a(`string`)

);

(async () {

  await fn(1) // Good

  await fn([1, 2]) // Bad

})();

```
