What is Debugging?
Step 1: Open Chrome Developer Tools
To access Chrome’s developer tools, you can either right-click on a web page and select “Inspect” or use the keyboard shortcut “Ctrl + Shift + I” (Windows/Linux) or “Cmd + Option + I” (Mac).
Step 2: Navigate to the Sources Tab
Once you’ve opened the Chrome developer tools, click on the “Sources” tab. This tab displays all of the scripts that are loaded on the current web page.
Step 3: Set a Breakpoint
Step 4: Start Debugging
Once you’ve set a breakpoint, reload the page to start debugging. When the code execution reaches the breakpoint, Chrome’s developer tools will pause the code and display the “Sources” tab. From here, you can step through the code line by line, examine variables, and watch the code execution in real-time.
Step 5: Use the Console
Step 6: Examine Network Activity
Step 7: Use the Elements Tab
Step 8: Identify Memory Leaks
Step 9: Use the Performance Tab
