请问这种js的什么语法?

wx.login({
  success (res) {
    if (res.code) {
      //发起网络请求
      wx.request({
        url: 'https://test.com/onLogin',
        data: {
          code: res.code
        }
      })
    } else {
      console.log('登录失败!' + res.errMsg)
    }
  }
})

微信小程序的初学者和js的初学者,请问这是js的什么语法?
wx.login({ })
{ }里面的内容作为参数传给login函数,然后login就会自动传给success函数res参数的值,然后sucess自动执行???
请问这是js的什么语法或者js的设计模式?或者是js的什么知识点?

回调函数(Callback)。把一个函数作为函数参数传给另一个函数。
