Conditional breakpoints can be very useful when debugging JavaScript code, as they allow you to pause execution only when certain conditions are met. Here's how to apply conditional breakpoints in the Chrome browser debugging tool: Open the Chrome DevTools by pressing F12 or right-clicking on a web page and selecting "Inspect". 1) Navigate to the "Sources" tab in the DevTools. 2) Find the JavaScript file that you want to debug in the file tree on the left-hand side. 3) Set a regular breakpoint by clicking on the line number where you want to pause execution. 4) Right-click on the breakpoint and select "Edit breakpoint" from the context menu. 5) In the breakpoint editor, enter the condition that you want to use to trigger the breakpoint. For example, you might enter a variable name and a value to pause execution only when the variable has a specific value. 6) Click "Save" to apply the conditional breakpoint. Now, when the code reaches the line with the conditional breakpoint, it will only pause execution if the condition is true. This can save you time and help you quickly identify issues in your code.
