Js Dom Manipulation in Javascript
DOM (Document Object Model) is the browser's representation of the HTML page as a tree of objects. JS can read and modify it.
Selecting elements: `getElementById()`, `querySelector()` (CSS selector), `querySelectorAll()` (all matches → NodeList).
Changing content: `.textContent = "..."` (text only), `.innerHTML = "..."` (HTML allowed but be careful with XSS).
Changing style: `.style.color = "red"`. Adding/removing classes: `.classList.add()`, `.classList.remove()`, `.classList.toggle()`.
Creating elements: `document.createElement("div")`. Appending: `parent.appendChild(el)` or `parent.append(el)`.
