After completing this unit, you’ll able to,
  • Add and Remove value in Array using Javascript.
So let’s get started,

Add value in Array
 var myArray=[];
 function add(){    
    myArray.push(yourValue);    
 }
Remove value from Array 
 var myArray=[];
 function remove(){    
    var index = myArray.indexOf(yourValue);
    if (index > -1) {
        myArray.splice(index, 1);
    }    
 }
Example: I am providing a complete code example using HTML page that let you know how this works for you.

        </head>
        <body>
            <input type="button" value="Add" onclick="add();"/>
            <input type="button" value="Remove" onclick="remove();"/>
            <br/>
            <div id="divValue">
            </div>
            <script>
            var i=0;
            var myArray=[];
            function add(){
                i++;
                myArray.push(i);
                document.getElementById("divValue").innerHTML=myArray;
            }
            
            function remove(){
                var index = myArray.indexOf(i);
                if (index > -1) {
                    myArray.splice(index, 1);
                }
                document.getElementById("divValue").innerHTML=myArray; 
                i--;
            }
