The Ultimate JavaScript DOM Crash Course (2022)

Welcome to the Ultimate JavaScript DOM Crash Course!

Let’s cut to the chase – here’s what you’ll be learning in this course:

selecting HTML elements

inspecting objects within the DOM and gaining a deeper understanding of what features and functions are available

getting data from HTML elements

updating HTML elements, including text content and adding more HTML

creating HTML elements – this one is important as it’s key to building interactive user interfaces

deleting HTML elements

adding events to your webpage to increase interactivity

and much more!

Once we’ve taken a look at the fundamentals, we’ll have a go at a practical example – building a sticky notes user interface with the JavaScript DOM. Don’t worry about the HTML and CSS, I’ll be providing that for you.

Learning how to interact with the JavaScript DOM, and having good knowledge of the methods and properties available to you is critical to becoming an exceptional front–end web developer, and I hope this crash course can give you an inspiring introduction to the diverse world of the JavaScript DOM.

Another thing to note – if you intend to begin building websites using front–end frameworks such as React or Vue, I highly recommend you watch this crash course first before doing so. Front–end frameworks are fantastic tools but it’s a good idea to have a solid understanding of the JavaScript DOM without those frameworks doing all the heavy lifting for you.
