butt v2.0.0

butt

If only there was a way to pass along a callback with exactly as many arguments as necessary.

You know how you like chaining asynchronous function calls but sometimes weird arguments get in the way of your waterfall series with unpredictable arguments?

How about attempting to parseInt in a map only to find out map spews three arguments? What if you could CONTROL THIS nonsense?

NO MORE!

npm install butt --save

Usage

Functional arguments giving you headaches?

Before

n.map(function (val) {
  return parseInt(val);
});

After

n.map(butt(parseInt, 1));

Works on .forEach or any functional array method as well! Classy.

Before

n.forEach(function (val) {
  console.log(val);
});

After

n.forEach(butt(console.log, 1));

Mongoose being weird?

Before

async.waterfall([
  function (next) {
    new User(model).save(function (err) {
      next(err);
    });
  },
  function (next) {
    // MOAR CODE
  }
])

After

async.waterfall([
  function (next) {
    new User(model).save(butt(next, 1));
  },
  function (next) {
    // MOAR CODE
  }
])

Why?

It had to be done. It is known.
