We see the Mouse-based events listed: click, dblclick, mouseout-over-enter-leave, etc. The above lists event breakpoints we can add to our script. These breakpoints let us add event breakpoints to our script. Using our above example, if we had stepped into the foo function body, pressing Step out would execute the whole body and return to line 5. Step out executes the whole current block and then moves out of the block. In our above example, pressing the Step in button on line 4: foo() will cause the execution to move into the foo function body in line 7. Step in causes the execution to move into the body of a function call or object. The program will execute the foo call and move to the next line. Pressing the step over button here will cause the foo call to execute without moving to the foo declaration at line 7. If we click the Step over button, the execution will move to line 4, which is a function call. Step over executes a line in the script and jumps over to the next line without stepping inside the statement. The Pause button pauses the execution of the script. The scopes show the variables attached to the window scope and the block scope, i.e., the scope of the current breakpoint.Īt the top of the scopes are buttons: Pause, Step over, Step in, Step out, and Resume. For example, onclick was called before the vibrate function.

The call stack shows the series of function calls that were made before arriving at the current breakpoint. If you look to the right, you will see the Breakpoints tab, which lists all the breakpoints in the current script. We click the Vibrate button and the script is executed and stops at line 47. v a l u e const time = vibTime.value co n s tt im e = v ib T im e. When we click the Vibrate button, the vibrate function will run and pause at line 47 where the statement reads c o n s t t i m e = v i b T i m e. You can add breakpoints in your script, which will cause your script execution to stop at those breakpoints. This tool is useful in debugging scripts.
