WCAG and OWASP indicate web development, probably front-end development.

You will want to learn the standard DOM methods. Walking the DOM as a tree structure as opposed to treating it as a database to query will increase your application capabilities. Learning to access the DOM without parsing a selector string will make your application many thousands of this new faster.

I only worked on front-end stuff for a year, but I can say walking the DOM and learning more about it was probably one of the most useful things.
