求大神解释
var person = {};
Object.defineProperties(person,{
title : {value : 'fe'},
crop : {value : 'BABA'},
salary : {value : 5000},
luck : {
get : function () {
return Math.random() > 0.5 ? 'good' : 'bad';
}
},
promote : {
set : function(level) {
this.salary *= level;
}
}
});
// var obj = Object.getOwnPropertyDescriptor(person,'luck');
// console.log(obj);
// console.log(person.salary);
person.promote = 2;
console.log(person.salary)
