Gain practical skills to create complex frontend components using HTML, CSS, and JavaScript in real-world applications.

Learn to apply your introductory knowledge of HTML, CSS, and JavaScript to build beautiful, real-world components. In this course, you'll go through the process of developing several complex components, including:

- eBay's dropdown menu
- Gmail's auto-validating form
- Google's main autocomplete enabled search
- Twitter's infinitely scrolling list
- Medium's tooltips

You'll learn how to approach common frontend challenges, what questions to ask yourself, how to design solutions once you've thought of them, how to debug and work with mistakes, and more.

The end-goal is to empower you to look at anything you see on a website and be able to say, "I can build that!"

Intermediate JavaScript: Building Frontend Components

The back end performs a lot of the difficult work of actually computing how to complete what you’ve typed, but we’re building the frontend component, so we’ll build upon a mock server.

We're going to be building a relatively straightforward but widely used version of autocomplete search: Google's main search.

In this lesson, we'll learn what the autocomplete functionality is and give a layout of the rest of the chapter
