# p-try [](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`.
