Let me share my new front-end web development secrets with you
Understanding the DOM will equip you to become an awesome front-end programmer. Learn how to implement your creative, different and dynamic ideas into your website. Master front-end development and you’re half way to becoming a full stack web developer. Take control through understanding. Delivering an interactive web experience is challenging.
How exactly does the browser model your HTML, CSS, and JavaScript? Where can we access this model? What can we do with this model? How can we change this model? By understanding these questions, you will be able to access the DOM and better yet, manipulate it! In other words, you will be able to create dynamic apps that improve user engagement and experience.
What This Course Covers
This is Course 1 of a 2-part program designed to provide you with a solid foundation in front-end web development. By the end of this course, you'll have a clear understanding of what the DOM is, how to access it, and how to manipulate it effectively. You’ll learn about nodes, HTMLCollections versus NodeLists, and much more!
In this course you’ll learn about front-end Web Development, by mastering the Document Object Model.
Why do you need to know about the DOM?
So, you know some HTML, you’ve created your first tags, learned about CSS, made awesome forms, star-gazing buttons, responsive pages and have started to create dynamic and interesting pages.
But now you want to do more: “How can I add animation (and life) to my page? I wish I could give an error message to a user who incorrectly submits a form!”
And this is where the DOM comes into the picture. and where this course(s) provide you with an opportunity to grow in your skills.
To cut a long story short, we use the DOM to allow users to interact with our app. It doesn’t have to be annoying interaction either – simple things like giving the user the ability to ADD/EDIT/DELETE/UPDATE contents on your page, for example, requires interaction with the DOM.
The first step in understanding the DOM is understanding what it is. How does it differ from your HTML markup? How does it differ from JavaScript? From there, you’ll start exploring and experimenting with tools to access the DOM. You’ll learn simple, yet very powerful strategies to access and traverse the DOM. We don’t stop here, but then get into more advanced things like manipulating the DOM (via the create and remove methods given to us by the DOM API).
Knowledge of the DOM is incredibly useful for understanding how your webpage can be improved.
By the end of this course, you'll be able to “speak” DOM by gaining an understanding of where you can find it, how you can access it, and more importantly, how you can manipulate it. We dig deeper in every lecture, learning about things like Nodes, the difference between HTTPCollections vs NodeLists, and a whole bunch more! This course has many bonus lectures which extend your knowledge base and test your skills.
Through practical examples, this course helps you understand the DOM piece by piece. And we use the latest and best features of JavaScript and browsers (like the new remove API) along the way so you can stay ahead of the pack.
*** A must-do Web Development course on Udemy ***
Successful programmers know more than rote learning a few lines of code. They also know the fundamentals of how your browser represents your HTML code and works behind the scenes. If you’re wanting to become a full stack developer, you need to know how to deal with the DOM. You need to know how to access it, how to manipulate it, and how to dynamically interact with it.
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.
Description
Hi there, my name is Clyde and together we’re going to learn how successful web developers can create whizbang websites that are dynamic and engaging!
The root to understanding how to be a professional front-end web developer is understanding the Document Object Model and applying it to practical situations. We're going to practice and learn and emerge confident to tackle any challenges modern programs and websites throw at us.
After completing a few university degrees, and post graduate studies, I developed a fascination for web design and software languages. For several years I have immersed myself in this. I spent a fair bit on top courses and went on to apply the knowledge practically. I recognized gaps in some of the courses I’ve taken and hence my course teaches what I wish I was taught. My intention is to share the knowledge with you in an easy to follow manner, so that we can benefit together. You benefit form learning, and I from sharing in your success.
This course is for beginners and for intermediates.
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 the fundamentals of the DOM 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 works behind the scenes – a skill that every full-stack developer needs to master.
In this course, I focus on true web development in the front end. This includes understanding what nodes are, looking at the Document node (this is different from the document object by the way), understanding the DOM tree structure, what the different types of nodes there are, and how you can use the DOM to access elements on your page and manipulate them.
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.
I love practical examples, which is why we build simple pages and analyze the DOM together.
Is This Course Right for You?
Absolutely!
This course is suitable for all levels.
If you fall into any of these categories, this course is perfect for you:

I appreciate my checkered past and often learnt things the hard way, through hard slog and trial and error.
I like to master what interests me, and share my successes with others.
My goal is to benefit my students most, to empower them with key knowledge and information not available in other courses.
A few words about me:
· I don’t care about titles
· Understanding means less mistakes later, and mistakes cost time
· My first computer was a box, installed with MS-DOS and Windows 95.
I'm an avid gamer
I’ve been coding for a long time. At the age of 7, in the early 90’s, I got my first pc and a few days later I became an avid gamer. I have always surrounded myself with coders. I still recall the days of floppy disks and playing “Doom”, “Duke Nukem” and of course one of my all-time favorites, “Red Alert”.
I’ve always been around computers, and that’s what makes my teaching style direct, to-the-point, and powerful!
Anyone can learn to write advanced code with the right attitude, and the right guidance. I invest 100% of my effort and thought into my students and how to present EVERY lecture to your advantage. I try to enhance your learning experience and accelerate your skill development. My aim is to teach you simply and clearly, in a fun way.
A big thank you to my students who continue to support me and provide ratings and feedback - I appreciate you.
