What This Course Covers

This advanced Document Object Model (DOM) course empowers you to take control through understanding. Crafting an interactive web experience can be challenging, but together we will explore the intricacies of DOM events.

I'll help you answer questions like What exactly are events? Why are they essential? What types of events can we listen for, and how does event bubbling and capturing work? By answering these questions and more, you’ll gain the skills to access and manipulate the DOM effectively, allowing you to create dynamic applications that enhance user engagement and experience.

This course is the second and final installment of a comprehensive 2-part program. While Course 1 lays the groundwork for coding dynamic sites, this Part 2 dives deeper into the world of DOM events. You’ll emerge with a solid understanding and practical experience in handling events within the DOM, setting you on the path to becoming a true Grandmaster in front-end web development.

Why You Need This Course

If you've ever wondered how to add animation and life to your web pages, understanding DOM events is crucial.

The DOM allows users to interact seamlessly with your application—enabling them to ADD, EDIT, DELETE, or UPDATE content without frustration. We’ll start by defining what an event is, distinguishing between event listeners and event handlers, and then explore various ways to implement events in your code.

We won’t stop there!

We’ll delve into advanced topics like event propagation (capturing vs. bubbling) and the powerful concept of event delegation. This course also covers essential subjects like DOM extensions and object hierarchy.

Knowledge is Power

By the end of this course, you'll be able to "speak" and "navigate" the DOM confidently, understanding how to manipulate it in meaningful ways. Each lecture digs deeper into essential topics, with bonus lectures that extend your knowledge base and challenge your skills.

Through hands-on examples, this course helps you grasp the DOM piece by piece while utilizing the latest JavaScript features (like the new classList API) so you can stay ahead of the curve.

*** An advanced Web Development DOM course on Udemy ***

Successful programmers know more than rote learning a few lines of code. They also know the fundamentals of how events work on your website behind the scenes. If you’re wanting to become a full stack developer, you need to know how to work with various events in the DOM. You need to know what an event is, how to listen for it, and more importantly, how to react to events when they happen.

I want you to become a successful front-end programming Grandmaster.

I want you to be able to apply what your learn in this course to your webpage.

This course is perfect for you.

A unique view

Understanding the DOM is a vast topic. To get you up to speed, I’ve spent months thinking about where to focus content and how to deliver it to you in the best possible way.

You will learn "why" things work and not just "how". Understanding advanced topics within the DOM (like event types, capturing, bubbling, delegation, host vs native objects, etc.) is important as it will give you infinite possibilities. Armed with this knowledge, you’ll be able to create applications that update the data of the page without needing a refresh. You will be able to create apps that are customizable by the user. You can even allow the user to drag, move, and delete elements. Can you begin to see how important the DOM is?

How is this course different?

There are lots of great courses that focus on web development. Pity they never get into the detail about how the Document Object Model (DOM) works behind the scenes – a skill that every full-stack developer needs to master.

In this Part 2 course, I focus on the more advanced topics of true web development in the front end. This includes understanding what events are, looking at object hierarchy, understanding the different event types, what capturing and bubbling is, and how you can use the concept of event bubbling to streamline your code and make your job of creating dynamic websites easier.

Practice makes perfect

Theory is theory … but there’s nothing like getting behind your computer and typing in code. That’s why we will be coding, laughing and pulling out our hair together as we code real life websites and exercises during this course in order to appreciate and master the DOM.

I love practical examples, which is why we build simple pages and analyze the DOM together.

This course is FULL of practical examples, challenges, and we even build an entire project website from start-to-finish (yep, this includes building the HTML and CSS together too).

Is This Course Right for You?

Absolutely! This course is suitable for all levels of web developers. If you identify with any of these categories, this course is perfect for you:

• You want to explore programming fundamentals and how JavaScript can enhance your web pages.

• You’re eager to learn how successful developers create engaging user experiences.
