JS: Partial Function Application

partial-function-application.js

function partial(func /*, 0..n args */) {
  var args = Array.prototype.slice.call(arguments, 1); // save all additional arguments to args (except index 0: func)
  return function() {
    var allArguments = args.concat(Array.prototype.slice.call(arguments)); //  then add arguments from the original function declaration
    return func.apply(this, allArguments);
  };
}
