Available on js
The PerformanceEntry
object encapsulates a single performance metric that is part of the performance timeline. A performance entry can be directly created by making a performance mark
or measure
(for example by calling the mark()
method) at an explicit point in an application. Performance entries are also created in indirect ways such as loading a resource (such as an image).
