basic Step implementation

ownstep.js

// this should work and give us 1 to 5
var Step = function (steps) {

  // this only works with arrays, @todo better check
  if (typeof steps !== 'object') {
    return;
  }

  var currentStep = 0, lastStep = steps.length;
    
  var execute = function () {
    var currentFn = steps[currentStep];
    currentStep++;
    
    // set execute to be the objects this pointer
    currentFn.call(execute);
  };

  execute();
};

var callback = function (fn) {
  console.log('inside callback and doin nasty stuff');
  fn();
};

Step([ 
    function () {
      console.log('nr. 1');
      callback(this);
    },
    function () {
      console.log('nr. 2');
      callback(this);
    },
    function () {
      console.log('nr. 3');
      callback(this);
    },
    function () {
      console.log('nr. 4');
      // callback(this);
    }
]);
