Adding Logs to Source Code

It’s tempting to liberally insert console.log() debugging statements throughout your files but logpoints provide a way to obtain the same information without writing any code.

To add a log point, open a script in the Sources panel, right-click any line number, and choose Add log point….

Enter an expression such as one you would use in a console command, e.g.

"The value of x is", x

The message will appear in the DevTools console whenever that line is executed. Log points will usually persist between page refreshes.
