Using get and set skillfully, you can directly operate object attributes to read and write, which can greatly improve programming efficiency. Here is a typical example:
var test = {
_Name : null,
_Age : 0,
//Reading and writing of _Name
set name(name) {this._Name = name;},
get name() {return this._Name;},
//Reading and writing of _Age
set age(age) {this._Age = age;},
get age() {return this._Age;}
}
alert(test.name " " test.age);//bull 0
test. name = 'lucy';
test.age = 20;
alert(test.name " " test.age);//lucy 20
