The Use of 'debugger' statement in JavaScript
In JavaScript, the debugger statement is a powerful tool for pausing code execution and launching the browser's built-in debugger . This allows you to inspect the state of your program at that specific point, examine variables, step through code line by line, and fix any bugs or errors. Here's a breakdown of its key uses: 1. Pausing Execution: When the debugger statement is encountered, code execution halts at that line. This gives you a chance to: Use the browser's debugger console to inspect variables , their values, and their types. Check the call stack to see how you got to that specific point in the code. Set breakpoints to pause execution at other points for further inspection. 2. Debugging: By examining variables and the program's state, you can identify the source of errors , logic flaws, or unexpected behavior. You can then modify the code or values, resume execution, and see if the issue is resolved. 3. Understanding Complex Code: For intricate logic or unfa
