Adding Elements

Manipulating the DOM often involves dynamically creating and adding new elements to the document or removing existing elements based on user interactions. Here, we will consider how to create and add elements dynamically.

Creating New Elements and Adding Them to the DOM

JavaScript provides methods like createElement(), appendChild(), and insertBefore() to create new elements and add them to the DOM.

CreateElement()

The createElement() method creates a new HTML element but doesn't add it to the DOM until you explicitly do so with methods like appendChild() or insertBefore().

AppendChild()

The appendChild() method adds a new child element to the end of a parent element's list of children. It's commonly used for adding elements to the bottom of a section, list, or container.

InsertBefore()

The insertBefore() method inserts a new element before a specified existing child element, allowing for more precise placement within a parent.
