Non-standard: This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.
Warning: Calling this API immediately after console.profile() can cause it to not work. To work around this, call it in a setTimeout with at least 5ms delay. See Firefox bug 1240249.
The console.profileEnd()
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.
Note: This feature is available in Web Workers
