console: profileEnd() static method

Non-standard: This feature is not standardized. We do not recommend using non-standard features in production, as they have limited browser support, and may change or be removed. However, they can be a suitable alternative in specific cases where no standard option exists.

Note: This feature is available in Web Workers.

The console.profileEnd() static method stops recording a profile previously started with console.profile().

You can optionally supply an argument to name the profile. Doing so enables you to stop only that profile if you have multiple profiles being recorded.

If console.profileEnd() is passed a profile name, and it matches the name of a profile being recorded, then that profile is stopped.
If console.profileEnd() is passed a profile name and it does not match the name of a profile being recorded, no changes will be made.
If console.profileEnd() is not passed a profile name, the most recently started profile is stopped.
