The Front-End Web Developer Bootcamp - HTML, CSS, JS, and React - DOM Get Methods

The video tutorial covers the use of DOM GET methods in JavaScript, including innerText, innerHTML, getAttribute, and attribute nodes. It demonstrates how to use these methods in a JavaScript file linked to an HTML file, emphasizing the importance of script placement for proper loading. The tutorial provides examples of using getElementById to access and manipulate HTML elements, and explains the differences between innerText and innerHTML. It also explores the getAttribute method for accessing element attributes and discusses the use of attribute nodes and values, advising against using nodes due to their limited importance.
