What is the process of property access and how does the subsequent line function?

I came across this code snippet on a JS tutorial page and I'm not entirely sure about its functionality. Could you please explain what this piece of code does?


// Original source: https://javascript.info/property-accessors

let user = {
  name: "John",
  surname: "Smith",

  get fullName() {
    return `${this.name} ${this.surname}`;
  },

  set fullName(value) {
    [this.name, this.surname] = value.split(" "); 
  }
};

// The "set fullName" function receives a specified value.

user.fullName = "Alice Cooper";

alert(user.name); // Alice
alert(user.surname); // Cooper

Answer №2

user.fullName = "Alice Cooper";

The code above assigns the value "Alice Cooper" to the `fullName` property of the `user` object.

set fullName(value) {
    [this.name, this.surname] = value.split(" "); <<<<<<<
}

When the `fullName` setter function is called, it uses the `split` method to separate the string "Alice Cooper" into an array based on the space character. This results in an array ["Alice", "Cooper"].

Next, this array is immediately broken down (destructured) and assigned to the `name` and `surname` properties of the `user` object.
