## :clipboard: Example



```js
const fnResult = require("fn-result");

// Simple sync function
fnResult(() => 42, (err, res) => console.log(res));
// => 42

// Same thing, but async
fnResult(
    cb => setTimeout(
        () => cb(null, 42)
      , 1000
    )
  , (err, res) => console.log(res)
);
// => 42

fnResult(() => { throw new Error("foo") }, err => console.log(err.message));
// => foo

let syncSquare = x => x * x
  , asyncSquare = (x, cb) => cb(null, x * x)
  ;

// Pass arguments to sync function
fnResult(syncSquare, [2], (err, res) => console.log(res));
// => 4

// Pass arguments to async function
fnResult(asyncSquare, [3], (err, res) => console.log(res));
// => 9

// Promise interface
fnResult(asyncSquare, [5]).then(res => {
    console.log(res);
});
// => 25

// Pass the scope
fnResult(function () {
    return this.world;
}, { world: "Mars" }, (err, res) => console.log(res))
// => Mars

// Pass args and scope to async function, with promise interface
fnResult(function (world, cb) {
    cb(null, `${this.msg} ${world}!`);
}, ["Pluto"], { msg: "Hello" }, (err, res) => console.log(res));
// => Hello Pluto!
```

## :sparkling_heart: Support my projects
I open-source almost everything I can, and I try to reply to everyone needing help using these projects. Obviously,
this takes time. You can integrate and use these projects in your applications *for free*! You can even change the source code and redistribute (even resell it).

However, if you get some profit from this or just want to encourage me to continue creating stuff, there are few ways you can do it:


 - Starring and sharing the projects you like :rocket:
 - [![Buy me a book][badge_amazon]][amazon]—I love books! I will remember you after years if you buy me one. :grin: :book:
 - [![PayPal][badge_paypal]][paypal-donations]—You can make one-time donations via PayPal. I'll probably buy a ~~coffee~~ tea. :tea:
 - [![Support me on Patreon][badge_patreon]][patreon]—Set up a recurring monthly donation and you will get interesting news about what I'm doing (things that I don't share with everyone).
 - **Bitcoin**—You can send me bitcoins at this address (or scanning the code below): `1P9BRsmazNQcuyTxEqveUsnf5CERdq35V6`

Thanks! :heart:
















## :dizzy: Where is this library used?
