In programming, errors can occur while writing code. It could be due to syntactical or logical errors. The process of finding errors can be time-consuming and tricky and is called code debugging.
Fortunately, most modern browsers come with built-in debuggers. These debuggers can be switched on and off, forcing errors to be reported. It is also possible to set up breakpoints during the execution of code to stop execution and examine variables. For this one has to open a debugging window and place the
One can also use the
const a = 5, b = 6; const c = a + b; console.log(c); // Result : c = 11;
Browser Developer Tools
Chrome DevTools: Google Chrome's developer tools offer a wide range of features for debugging web applications.
Firefox DevTools: Mozilla Firefox's developer tools are another excellent option, offering similar capabilities.
Microsoft Edge DevTools: For Microsoft Edge users, the built-in developer tools provide essential debugging features.
Safari Web Inspector: Safari's Web Inspector is a robust toolset for debugging and profiling web applications.
Modern browsers offer developer tools with debugging capabilities. Set breakpoints to pause code execution and inspect variables and call stacks. Step through code to understand its flow. Browser Developer Tools
You can access them by right-clicking on a web page and selecting "Inspect" or by pressing
Key features include:
Console: View and interact with console output.
Elements: Inspect and modify the DOM.
Network: Monitor network requests and responses. Using debugger Statement
Insert the debugger statement in your code to create breakpoints programmatically. When the code encounters debugger, it will pause execution and open the browser's developer tools.
