Question

What advantages does JavaScript have?

Answer 1

Some advantages of JavaScript are:

1. Lower interaction with the server: With the help of JavaScript, you will be able to validate any user-based input before you send off the page to the server. 
2. Instant feedback to visitors: Visitors can immediately find out if they forgot to enter anything even before the page reloads. 
3. Increase in Interactivity: With JavaScript, you can create different interfaces which can react once the user hovers the mouse over them or uses the keyboard to activate them.
