> Start a promise chain

[How is it useful?](http://cryto.net/~joepie91/blog/2016/05/11/what-is-promise-try-and-why-does-it-matter/)

## Install

```sh

npm install p-try

```

## Usage

```js

import pTry from 'p-try';

try {

	const value = await pTry(() => {

		return synchronousFunctionThatMightThrow();

	});

	console.log(value);

} catch (error) {

	console.error(error);

}

```

## API

### pTry(fn, ...arguments)

Returns a `Promise` resolved with the value of calling `fn(...arguments)`. If the function throws an error, the returned `Promise` will be rejected with that error.

Support for passing arguments on to the `fn` is provided in order to be able to avoid creating unnecessary closures. You probably don't need this optimization unless you're pushing a *lot* of functions.

#### fn

The function to run to start the promise chain.

#### arguments

Arguments to pass to `fn`.
