聊聊Angular+Service如何改进日志功能

import { Injectable } from '@angular/core';
@Injectable({
  providedIn: 'root'
})
export class LogService {

  constructor() {

  }
  trace(...data: any[]): void {
    console.trace(data);
  }
  log(...data: any[]): void {
    console.log(data);
  }
}

logService.log('console executed from AppComponent');

import { Injectable } from '@angular/core';
@Injectable({
  providedIn: 'root'
})
export class LogService {

  constructor() {

  }
  trace(source: string, ...data: any[]): void {
    console.trace(data);
  }
  log(source: string, ...data: any[]): void {
    console.log(data);
  }
}

logService.log('AppComponent','console executed from AppComponent');
