DEP0152：扩展 PerformanceEntry 属性

【DEP0152: Extension PerformanceEntry properties】

类型：运行时

【Type: Runtime】

'gc'、'http2' 和 'http' <PerformanceEntry> 对象类型被分配了额外的属性，这些属性提供了额外的信息。这些属性现在可以通过 PerformanceEntry 对象的标准 detail 属性获取。现有的访问器已被弃用，不应再使用。

【The 'gc', 'http2', and 'http' <PerformanceEntry> object types have additional properties assigned to them that provide additional information. These properties are now available within the standard detail property of the PerformanceEntry object. The existing accessors have been deprecated and should no longer be used.】
