			# p-try [![Build Status](https://travis-ci.org/sindresorhus/p-try.svg?branch=master)](https://travis-ci.org/sindresorhus/p-try)

			> 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

			```
			$ npm install p-try
			```


			## Usage

			```js
			const pTry = require('p-try');

			(async () => {
			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`.
