Requirements
Chrome Developer Tools (DevTools) is a set of web developer tools built directly into the Google Chrome browser, offering developers deep access into the internals of their web applications and the web itself.
The course is designed for web developers and designers looking to harness the full potential of Google Chrome’s Developer Tools. This course will, empower participants to enhance their web development workflow, debug and optimize their code, and create more efficient and effective web applications.
Throughout the course, learners will embark on a comprehensive journey, beginning with an introduction to the various panels and options within Chrome Developer Tools. Participants will gain hands-on experience in simulating mobile devices, allowing for responsive design testing directly within the browser. The course delves into the nuances of working with the Element Panel, teaching learners how to manipulate the DOM and style elements in real-time, fostering a deeper understanding of the webpage rendering process.
Setting up persistence in DevTools is another crucial skill covered, ensuring that changes made during debugging sessions can be retained. The course also offers insights into editing and examining the box model, enabling participants to tweak layout and design with precision.
A portion of the course is dedicated to mastering JavaScript debugging techniques. Learners will follow a structured approach to identifying and fixing bugs, starting from reproducing the issue to applying the final fix. This process includes pausing code execution with breakpoints, stepping through code to understand its execution flow, setting additional breakpoints for closer examination, checking variable values to identify discrepancies, and ultimately, applying the necessary corrections.
Additionally, the course covers the use of the Console for executing JavaScript in the context of the current page and explores the Network panel to analyze and optimize load times and resource requests. Other DevTools panels are also explored, providing a well-rounded understanding of the tools available to web developers.
By the end of the course, participants will have developed a mastery of Chrome DevTools, enabling them to debug efficiently, optimize performance, and deliver high-quality web applications.
