Are you tired of the never-ending search for bugs in your JavaScript code? Do you wish there was a way to debug your code with ease? Well, look no further! In this blog post, we will explore some of the best tools and techniques to make debugging JavaScript a breeze. 🌬️

Console Logging 📄

Console logging is a simple yet powerful technique that developers can use to monitor the behavior of their code. By using console.log(), we can print messages to the console and see how our code is executing. This technique works by inserting statements into the code, and each statement can contain a message or variable values that are logged when the code is executed.

To use console.log(), simply insert it into your code where you want to log something. You can also use console.error(), console.warn(), and console.info() to log different types of messages.

Chrome DevTools 🛠️

Chrome DevTools is a built-in debugging tool that comes with the Google Chrome browser. It allows developers to inspect and edit their code on the fly, all while the code is running. With Chrome DevTools, you can:

  • Set breakpoints and step through your code
  • Examine variables and object properties
  • View and control the call stack
  • Inspect network activity and debug performance issues
  • Edit HTML, CSS, and JavaScript in real-time
