This chapter introduces DOM Manipulation, one of the most important skills for front-end JavaScript developers.
DOM stands for Document Object Model. It represents the structure of a web page. Using JavaScript, you can access HTML elements, change their content, update styles, and respond to user actions.
DOM manipulation is what makes websites interactive. Without it, web pages would only display static content. With it, developers can build forms, sliders, popups, validation systems, and dynamic interfaces.
In this chapter, students will learn how to:
- Understand what the DOM is and how it works
- Select HTML elements using JavaScript
- Change text, HTML, and styles dynamically
- Handle user events like clicks and input
- Create, remove, and update elements
- Build interactive features using JavaScript
By the end of this chapter, students will be able to control web pages using JavaScript and build real, interactive applications — a key step toward becoming a job-ready front-end developer.
