vue2项目升级成vue3 created方法

Question

问题遇到的现象和发生背景

vue2项目升级成vue3

用代码块功能插入代码，请勿粘贴截图

vue2中的代码

  created: function () {
    this.getAllFlowCategoryData()
    this.userId = this.$store.state.user.info.userId
    this.getDoingCount()
    this.getSentCount()
    this.getDoneCount()
    this.getTodoCount()
    this.getAntThisWeekDoneInfo()
  },

我的解答思路和尝试过的方法

const created = () => function (){
  console.log('aaaa')
}

我想要达到的结果

vue3中有什么方法，可以实现created（）的效果嘛
