  var i;
  va

  {
    text+="The number is "+i+"<br>";
}

    <script>
    var fruit = ["Apple", "Orange", "Mango", "Pineapple"];
    var i;
    var text="";
    for(i=0; i<fruit.length; i++)
    {
        text+=fruit[i] +"<br>";
    }
    document.getElementById("demo").innerHTML=text;
    </script>

    <p id="demo"></p>
    <script>
    var txt="";
     var person={fname:"John", lname:"Doe", age:"25"};
     var x;
     for (x in person) {
         txt += person[x]+" ";
     }
document.getElementById("demo").innerHTML=txt;
