All major browsers include developer tools, which enable developers to examine the code of a webpage or app, as well as run tests and evaluate metrics related to that code. Chrome Developer Tools (DevTools for short) is the industry standard. Explore how the tools work in actual testing and debugging scenarios and get an expanded toolbox for your day-to-day work. This course teaches the most widely used parts of DevTools, using sample files to walk through identifying issues and bugs, fixing them, and then verifying that they've been fixed. Each chapter digs into a different tool, including the Console, Elements panel, and Network panel, exploring how it's useful and when to use it. Author and educator Sasha Vodnik helps you explore the DOM, examine errors, look at source files, identify bottlenecks in page loads, and more.
