Break on Function javascript

Break on function javascript is a debugging technique that allows you to set a breakpoint at a specific function in your code. When the function is executed, the debugger will pause the execution of your code at that point, giving you a chance to inspect the state of your code and debug any issues that may arise.

How to set a breakpoint on a function in JavaScript?

There are several ways to set a breakpoint on a function in JavaScript:

Using the debugger keyword
Using the Chrome DevTools Debugger
Using Visual Studio Code Debugger

Using the debugger keyword

You can set a breakpoint on a function in your code by using the debugger keyword. This will cause the browser to pause execution of your code when it reaches that line, allowing you to inspect the current state of your application.


function myFunction() {
  debugger;
  // Your code here
}

Using the Chrome DevTools Debugger

You can also set a breakpoint on a function using the Chrome DevTools Debugger. To do this, open up the DevTools window and navigate to the Sources panel. Find the function you want to set a breakpoint on and click on the line number to add a breakpoint.


<div class="example">
  <script src="script.js"></script>
</div>

Using Visual Studio Code Debugger

You can also set a breakpoint on a function using the Visual Studio Code Debugger. To do this, open up your code in VS Code and navigate to the function you want to set a breakpoint on. Click on the line number to add a breakpoint.


<div class="example">
  <script src="script.js"></script>
</div>

Conclusion

Break on function javascript is a powerful debugging technique that can help you resolve issues in your code more quickly and efficiently. Whether you use the debugger keyword, Chrome DevTools Debugger or Visual Studio Code Debugger, setting a breakpoint on a function can help you better understand the behavior of your code and find any issues that may be present.
