Vanilla jаvascript: Building on the Document Object Model (DOM)

At the heart of every web app lies the DOM, the Document Object Model. jаvascript programs can modify this tree of structured content, letting users interact with and change the contents of documents. In this course, instructor W. Scott Means shows you how to find things in the tree, leap from point to point, and make changes to content and structure. Scott explains several key DOM concepts, including the Node interface, DOM-specific maps and lists, queryall++, and more. He covers where the DOM comes from and how to parse HTML to DOM. Scott describes tree traversal, as well as processing document fragments, comments, elements, and more. He concludes with advice on how you can practice what you've learned and get one step closer to mastering the DOM.
