Front-end web development is a wide and varied field that allows us to create not only well-designed, responsive websites, but also useful web applications that can be used in our daily lives. In the last course of this web development track, you will use all your knowledge of HTML and CSS as well as learn advanced JavaScript concepts to build a series of web applications including a weather app, a stopwatch app, and a calculator. In addition, you will learn what APIs are, how they are used to collect information, and how you can integrate them into your own websites.
