When
the debugger is turned on, then debugger statement pauses the execution of JavaScript
application.
HelloWorld.html
<!DOCTYPE html> <html> <body> <p>Click on the buttons to perform Arithmetic Operations</p> <button onclick="sum()">Add Numbers</button> <p id="demo"></p> <script> function sum() { var input1 = parseInt(prompt("Enter first Argument", 0)); var input2 = parseInt(prompt("Enter Second Argument", 0)); var result = input1 + input2; //When the debugger is turned on, then the application pauses here debugger; console.log("Sum of %d and %d is %d", input1, input2, result); document.getElementById("demo").textContent = "Result : " + result; } </script> </body> </html>
Load
application in browser and turn on the debugger. After entering the inputs to
the application, you can observe control stops at debugger statement.
