// Same thing, but async
fnResult(
    cb => setTimeout(

    )
  , (err, res) => console.log(res)
);
// => 42
 
fnResult(() => { throw new Error("foo") }, err => console.log(err.message));

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));

💖 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 🚀

• —I love books! I will remember you after years if you buy me one. 😁 📖

• —You can make one-time donations via PayPal. I'll probably buy a coffee tea. 🍵

• —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! ❤️
