1 Benefits of browser dev tools

One of the main benefits of browser dev tools is that they allow you to see and modify the HTML, CSS, and JavaScript of the web page in real time. You can use the inspector tool to select any element and view its properties, styles, and events. You can also use the console tool to execute JavaScript commands, log messages, and catch errors. This way, you can experiment with different code changes and see the results instantly, without reloading the page or saving the file.

* Debugging (already pointed out) - inspecting and manipulating the HTML, CSS, and JavaScript code in real-time. * Profiling - dev tools can be used to profile web pages by providing information about the performance of the page: load times, memory usage, network requests. * Testing/Emulation - dev tools can test/emulate web pages as different browsers and devices. * Optimization - dev tools can suggest how to improve the performance of the page. These suggestions can include things like reducing the number of resources that are loaded, minifying the code, and using caching.

Additionally, browser dev tools are invaluable for quick prototyping during calls and presentations, especially in situations where writing code from scratch would be time-consuming and laborious. These tools enable you to make swift edits directly in the browser, allowing you to add or remove HTML, CSS, or JavaScript components effortlessly. This real-time capability empowers you to witness instant changes and bring ideas to life rapidly, without the need to reload the entire page or save the file. With the ability to modify code on the fly, browser dev tools offer a seamless and efficient way to make things happen with remarkable speed during collaborative sessions and presentations.

2 Challenges of browser dev tools

One of the main challenges of browser dev tools is that they are not consistent across different browsers. Each browser has its own set of dev tools, with different features, interfaces, and shortcuts. For example, Chrome dev tools have a network tab that shows the requests and responses of the web page, while Firefox dev tools have a network monitor that does the same. Some dev tools may also have more advanced or specialized functions than others, such as accessibility audits, performance analysis, or device emulation. Therefore, you may need to switch between different browsers and dev tools to test and debug your web page for different scenarios and platforms.

Testing web apps on real devices and using web dev tools to inspect them has limitations that can make the process trickier. Accessing and connecting to real devices for testing can be challenging, while web dev tools may not fully replicate device-specific behavior. Debugging and inspecting on real devices can be cumbersome due to screen size and input limitations. Despite these challenges, testing on real devices and using web dev tools is important for ensuring optimal functionality and user experience across platforms and configurations.

3 How to access browser dev tools

To access browser dev tools, you can use keyboard shortcuts, menu options, or right-click options. The most common keyboard shortcut is F12, which opens the dev tools in a separate window or a panel at the bottom of the browser. You can also use Ctrl+Shift+I (or Cmd+Option+I on Mac) to open the dev tools in the same shortcut. Alternatively, you can use the menu option of the browser, such as Tools, More Tools, or Developer, and select Developer Tools or Web Inspector. Another option is to right-click on any element on the web page and select Inspect or Inspect Element.

Browser dev tools can be extremely useful for finding bugs and monitoring performance of a web page. Breakpoints are very helpful in determining the states of different variables at different stages of execution. Additionally, adding logs to display information when code has been run can help you focus on the right parts of the code when debugging.
