for loop

//data type with length
var x = [1,2,3,4,5,5,5,5,5,5,5,5,5,5,5,6,7,7,10];

var i
  ,content;

for(i = 0; xlength; i < content; i ++){
   console.log(x[i]);
}

//loop through an object literall
    var statContainer = {
        "rolledStats" : {
            "strength" : "7",
            "dexterity" : "12",
            "constitution" : "4",

            "wisdom" : "16",
            "charisma" : "9"
        }
    };

  //proper method to avoid primitive object's prototype.
      for (var key in statContainer) {
          if (statContainer.hasOwnProperty(key)) {
              var obj = statContainer[key];

                  if (obj.hasOwnProperty(prop)) {
                      console.log(prop + " = " + obj[prop]);
