In this tutorial we will create a Add New Row In Table using JavaScript. This code will dynamically add a new table row when the user click the add button. The code use onclick() function in order to launch a method that can generate a new table row using appendChild() as dot notation in the parent element. You can apply this script to your code to make your transaction faster, it is a user-friendly program feel free to modify it. We will use JavaScript to add some new feature to the website interface by actually written into an HTML page. It is what gives your page a different interactive elements and animation that engage a user.
