update the HTML DOM using JavaScript

Here in this tutorial I've explained a simple way to update the HTML DOM element by using JavaScript programming language.
I took one input box and a submit button and our goal is to print the user input value in the below span when the submit button is clicked.

Key-Points
-------------------
- Selecting an element & getting value
- If...Else... condition
- Printing value to DOM
