Finding Forms in HTML Page using javascript

We can find how many form element we are using in a HTML page using document.forms.length by using JavaScript DOM ELEMENTS.

<form>
        FirstName: <input type="text" />
    </form><br />
    <form>
        LastName:<input type="password" />
    </form>
    <p id="demo"></p>
    <script>
        document.getElementById('demo').innerHTML = "Number of Forms in the page :" + document.forms.length;
    </script>

Here we have taken two forms in the page , so it displays 2 in the output

OUTPUT
Number of forms in the page:2
