Object是一个无序的集合,可以存放任意类型对象,所有其他对象都继承自这个对象。 创建Object类型有两种,一种是使用new运算符,一种是字面量表示法。 1.使用new运算符创建Object varobj =newObject();//注意大写,也可以直接写成Object() 注意,通过new Object()的写法生成新对象,与字面量的写法obj = {}是等价的。
sort(compareNames); console.log(objArr);Defining comparison function for comparing numbers even much easier. To compare numbers instead of strings, the compare function can subtract b from a. Here's an example that shows how to sort an array of object by numeric property values in ascend...
