Ajax调用后未定义

I have an ajax function that returns data and I want to push the objects name into an array but when I check the console, it keeps saying undefined. How can I print the certain attribute only?

$.ajax({
      url: 'http://localhost:3000/list',
      type: 'get',
      success: function(response){
        console.log(response);
        console.log(response.name);
      },
      error: function(){
        console.log('err');
      }
    });

When I check the results on console

//console.log(response);
(3) [{...}, {...}, {...}]
1: {_id: "1", name: "a"}
2: {_id: "2", name: "b"}
3: {_id: "3", name: "c"}

//console.log(response.name);
(3)undefined

    Your response is an object so you must identify the index of what you want to display

      console.log(response[1].name); //will display "b"
