This real-time feedback allows you to iterate faster and catch errors before they become a headache. As you write your code, you can instantly see the outcome, making debugging and testing a breeze. One of the key features of our JavaScript Online Compiler is the live view coding result. These templates cover a wide range of topics and are tailored to help you grasp essential JavaScript concepts effortlessly. With ready-to-use templates, you can quickly kick-start your projects and learn by example. ![]() The debugging process may be a bit different but the concept behind debugging is the same.The JavaScript Online Compiler offers an intuitive user interface, making it easy for beginners to learn and practice their coding skills. However, it's not your only option.Īll good IDEs provide a way for you to debug the code. In the above methods, we have used the Chrome browser to show the debugging processes for simplicity. Here, you just set breakpoints by clicking on the line number of the source code instead of manually calling the debugger function. Setting breakpoints is similar to putting a debugger in the code. You can set breakpoints through the Developers tool anywhere in the code. Let's see an example by setting a breakpoint in the Chrome browser. Then, you can resume the execution of code. JavaScript will stop executing at each breakpoint and lets you examine the values. You can set breakpoints for JavaScript code in the debugger window. The rest of the code will execute when you resume the script by pressing play in the console. You can then resume the flow control after examining the program. The above program pauses the execution of the program in the line containing the debugger. Let's see how you can use debugger in a Chrome browser. The debugger is available in almost all JavaScript engines. The debugger keyword stops the execution of the code and calls the debugging function. It's also available in other JavaScript engines. The console.log() is not specific to browsers. Working of console.log() method in browser Using console.log() method in the browser opens the value in the debugger window. However, you can also use this method for debugging. ![]() In the previous tutorial, we used console.log() method to print the output. You could pass the object in console.log() or simply a message string. To open the debugging section of CDT, select View > Developer > JavaScript Console, and then go to the Sources tab. The syntax is: console.log(object/message) You can pass the value you want to check into the console.log() method and verify if the data is correct. You can use the console.log() method to debug the code. There are different ways you can debug your JavaScript program. It is essential that you know how to debug your code and fix errors.ĭebugging is the process of examining the program, finding the error and fixing it. In fact, most of the time, they help us identify issues with our code. ![]() You can and will encounter errors while writing programs. ![]()
