var person = {}; alert(typeof person); //object Object.defineProperty(person,"name",{ writable:true, value:"Yoyo" }); alert(person.name); //Yoyo person.name = "Anne"; alert(person.name); //Anne
var person = {}; Object.defineProperty(person,"name",{ configurable:false, value:"Yoyo" }); alert(person.name); //Yoyo delete(person.name); alert(person.name); //Yoyo
var person = {}; Object.defineProperty(person,"name",{ configurable:true, value:"Yoyo" }); alert(person.name); //Yoyo delete(person.name); alert(person.name); //undefined
