Operation of the array

• Create an array
• <script>
  var i;
  var mycars = new Array ();
  Mycars[0] = "Saab";
  MYCARS[1] = "Volvo";
  MYCARS[2] = "BMW";
  for (i=0;i<mycars.length;i++) {
  document.write (Mycars[i] + "<br/>");
  }
  </script>
• Merging two arrays-concat ()
• <script>
  var hege = ["Cecilie", "Lone"];
  var stale = ["Emil", "Tobias", "Linus"];
  var children = Hege.concat (stale);
  document.write (children);
  </script>
• Merging three arrays-concat ()
• <script>
  var parents = ["Jani", "Tove"];
  var = ["Stale", "Kai Jim", "Borge"];
  var children = ["Cecilie", "Lone"];
  var family = Parents.concat (children);
  document.write (family);
  </script>
• Make a string of elements of an array-join ()
• <script>
  function MyFunction () {
  var fruits = ["Banana", "Orange", "Apple", "Mango"];
  var X=document.getelementbyid ("demo");
  X.innerhtml=fruits.join ();
  }
  </script>
• Delete the last element of an array-pop ()
• <script>
  var fruits = ["Banana", "Orange", "Apple", "Mango"];
  function MyFunction () {
  Fruits.pop ();
  var X=document.getelementbyid ("demo");
  X.innerhtml=fruits;
  }
  </script>
• Add a new element to the end of the array-push ()
• <script>
  var fruits = ["Banana", "Orange", "Apple", "Mango"];
  function MyFunction () {
  Fruits.push ("Kiwi")
  var X=document.getelementbyid ("demo");
  X.innerhtml=fruits;
  }
  </script>
• Reverses the order of elements in an array-reverse ()
• <script>
  var fruits = ["Banana", "Orange", "Apple", "Mango"];
  function MyFunction () {
  Fruits.reverse ();
  var X=document.getelementbyid ("demo");
  X.innerhtml=fruits;
  }
  </script>
• Delete the first element of an array-shift ()
• <script>
  var fruits = ["Banana", "Orange", "Apple", "Mango"];
  function MyFunction () {
  var Delell = Fruits.shift ();
  var X=document.getelementbyid ("demo");
  X.innerhtml= ' Delete after array is: ' + fruits;
  document.getElementById ("Demo2"). Innerhtml= ' deleted elements are: ' + Delell;
  }
  </script>
• Select elements from an array-slice ()
• <script>
  function MyFunction () {
  var fruits = ["Banana", "Orange", "Lemon", "Apple", "Mango"];
  var citrus = Fruits.slice (1,3);
  var X=document.getelementbyid ("demo");
  X.innerhtml=citrus;
  }
  </script>
• Array sort (ascending alphabetical order)-sort ()
• <script>
  function MyFunction () {
  var fruits = ["Banana", "Orange", "Apple", "Mango"];
  Fruits.sort ();
  var X=document.getelementbyid ("demo");
  X.innerhtml=fruits;
  }
  </script>
• Sort by number (ascending in numeric order)-sort ()
• <script>
  function MyFunction () {
  var points = [40,100,1,5,25,10];
  Points.sort (function (A, b) {return-A-b});
  var X=document.getelementbyid ("demo");
  x.innerhtml=points;
  }
  </script>
• Sort by number (descending in numeric order)-sort ()
• <script>
  function MyFunction () {
  var points = [40,100,1,5,25,10];
  Points.sort (function (A, b) {return b-a});
  var X=document.getelementbyid ("demo");
  x.innerhtml=points;
  }
  </script>
• Add an element to the 2nd position of the array-splice ()
• <script>
  function MyFunction () {
  var fruits = ["Banana", "Orange", "Apple", "Mango"];
  Fruits.splice (2,0, "Lemon", "Kiwi");
  var X=document.getelementbyid ("demo");
  X.innerhtml=fruits;
  }
  </script>
• Convert array to string-tostring ()
• <script>
  function MyFunction () {
  var fruits = ["Banana", "Orange", "Apple", "Mango"];
  var str = fruits.tostring ();
  var X=document.getelementbyid ("demo");
  X.innerhtml= str;
  }
  </script>
• Add a new element at the beginning of the array-unshift ()
• <script>
  function MyFunction () {
  var fruits = ["Banana", "Orange", "Apple", "Mango"];
  Fruits.unshift ("Lemon", "Pineapple");
  var X=document.getelementbyid ("demo");
  X.innerhtml=fruits;
  }
  </script>
