18const pTry = require('p-try');
19
20(async () => {
21 try {
22 const value = await pTry(() => {
23 return synchronousFunctionThatMightThrow();

33## API
34
35### pTry(fn, ...arguments)
36
37Returns 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.
38
39Support 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.
40
41#### fn
42
43The function to run to start the promise chain.
44
45#### arguments
46
47Arguments to pass to `fn`.
