PerformanceEntry

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).

interface PerformanceEntry {

readonly duration: DOMHighResTimeStamp;

readonly entryType: string;

readonly name: string;

readonly startTime: DOMHighResTimeStamp;

toJSON(): any;

}

var PerformanceEntry: {

prototype: PerformanceEntry;

new (): PerformanceEntry;

};
