Why is DOM important?

DOM (Document Object Model) is important because it provides a structured representation of a web page that JavaScript and other scripts can interact with.

The DOM allows developers to:

• Access and modify HTML elements
• Change content and styles dynamically
• Respond to user interactions, such as clicks and form submissions
• Create or remove elements
• Build interactive web experiences
• Update page content without fully reloading the page

For example, JavaScript can use the DOM to change a product’s displayed price, update a shopping cart, or show a message when a customer clicks a button.

In short, the DOM acts as the bridge between a web page’s HTML structure and JavaScript behavior, making dynamic and interactive websites possible.
