// 35ms | total: 35ms | calls: 1 | MyMethods:slowMethod
import {isDevMode} from '@angular/core';
export function LogPerformance(whenExceedsTimeInMs: number = 30, whenExceedsCalls: number = 50): any {
return function<T>(target: T, key: keyof T, descriptor?): any {
descriptor =
descriptor || Object.getOwnPropertyDescriptor(target, key) || Object.getOwnPropertyDescriptor(Object.getPrototypeOf(target), key);
