Question

What are javascript accessors?

Answer 1

ECMAScript 5 introduced javascript object accessors or computed properties through getters and setters. Getters uses the get keyword whereas Setters uses the set keyword.

var user = {
  firstName: "John",
  lastName: "Abraham",
  language: "en",
  get lang() {
    return this.language;
  },
  set lang(lang) {
    this.language = lang;
  },
};
console.log(user.lang); // getter access lang as en
user.lang = "fr";
console.log(user.lang); // setter used to set lang as fr
