fn-declare

fn-declare lets you dynamically define a function with the amount of parameters you want.

You might need this behaviour if external library is forcing you to declare some amount of parameters inside a function but you prefer some generic approach using arguments

Usage

To get a function definition with 2 parameters:

var fnDeclare = require('fn-declare');
var fnWithDefinedParameters = fnDeclare(2, function(){
  console.log(arguments);
});

fnWithDefinedParameters('a', 'b') => prints ['a', 'b']

Eventually fnDeclare(2, function someCallback(){}) returns a function which is the same as if a callback was defined with explicit parameters

function someCallback(p1, p2, p3){
  //some code using arguments. 
}
