Getters and Setters in a function (javascript)

Question

When using get in an object like this, get works:

var people = {
  name: \"Alex\",
  get say         


        

Answer 1

You can use the actual get and set keywords only in classes (ES2015) and object literals.

ECMAScript 5

In ES5, your would typically use Object.defineProperty to implement what you're trying to achieve:

function People2() {
    this.name = "Mike";
}
Object.defineProperty(People2.prototype, "sayHi", {
    get: function() {
        return "Hi, " + this.name + "!";
    }
});

ECMAScript 2015

In ES2015, you could also use classes to achieve the desired behavior:

class People2 {
    constructor() {
        this.name = "Mike";
    }
    get sayHi() {
        return `Hi, ${this.name}!`;
    }
}
