Events are actions taken by a user such as clicking a button or hovering over an element on a page. Events can also be generated by code — for example when an Ajax request completes or when an element reaches a specific position on a page. Events are an important tool in modern web development as they allow developers to create interactive experiences for their users.
Event handlers allow developers to respond when an event occurs — they are functions that execute whenever an event is triggered. All modern browsers support certain events such as mouse events and key events, but some browsers may not support certain events such as animation events or touch events.

Debugging and Troubleshooting Your Code
Debugging is a powerful skill that all developers should have – it involves detecting and solving problems in the code you have written. There are various techniques you can use when debugging your code – adding console logs where necessary in order to track down errors quickly, using step-by-step debugging to track down errors one at a time, using automated testing tools, and more.
Best Practices for Writing Clean Code
Writing clean, efficient code is essential for making easy-to-read code that performs better. By adhering to best practices such as keeping variable names descriptive, avoiding repetition by writing DRY (Don’t Repeat Yourself) code, following coding conventions, writing modular code that can be reused across programs, etc., you will be able to write cleaner code that makes debugging much easier.
