Creating and Adding Elements
You can create brand new elements with JavaScript and add them to the page dynamically. This is how single-page apps and interactive features work.
The main steps: create the element, configure it (text, attributes, classes), then insert it into the DOM.
Creating an Element
Use document.createElement(tagName).
Appending Elements
Use appendChild (add to end), prepend (add to beginning), or insertBefore.
Creating Multiple Elements
Loop to create many, or use innerHTML for quick markup.
Using innerHTML to Add Markup

Removing Elements
Use remove() or parent.removeChild(child).
