In this tutorial we will create a Display Random Table Content using JavaScript. This code will display random content in the table when user click the button. The code use JavaScript onclick() to call a specific function that will display the array of object by the use of for() loop, and then rearrange the index position of an array by using array.splice(). You can apply this script to your system that use image gallery, this 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.
