javascript - Was bedeutet diese JS-Anweisung?

Question

Bitte sagen Sie mir, was diese JS-Aussage bedeutet?

    var aa= {},
        bb= [{name: 'aa1'},{name: 'aa2'}];

Code oben.

Answer 1

等价于

var aa = {};
var bb = [{name: 'aa1'},{name: 'aa2'}];

等价于

var aa;
var bb;
aa = {};
bb = [{name: 'aa1'},{name: 'aa2'}];

给 aa 初始化为一个空对象，给 bb 初始化为一个数组，含有两个对象

Answer 2

声明aa是个空对象，bb是个数组，数组里有两个对象属相是name，值分别为aa1和aa2
