    Debugging JavaScript in Chrome can be done using the Chrome DevTools. This tool provides a comprehensive environment for inspecting and debugging your code. Here’s a step-by-step guide to enable and use script debugging in Chrome.

    Opening Chrome DevTools

    1. Open Chrome and navigate to the page you want to debug.

    2. Open DevTools by pressing F12 or Ctrl + Shift + I (Windows/Linux) or Cmd + Opt + I (Mac).

    3. Navigate to the Sources panel. This panel is where you will find the tools necessary for debugging JavaScript.

    Setting Breakpoints

    Breakpoints allow you to pause the execution of your code at specific points to inspect variables and the call stack.

    1. Open the Sources panel.

    2. Locate your JavaScript file in the File Navigator pane.

    3. Click on the line number where you want to set a breakpoint. A blue icon will appear, indicating that a breakpoint has been set.
