I'm struggling to make sense of this syntax, could someone kindly clarify for me?

const players = [
    {
        name: "alice",
        team: "yellow",
        points: 15,
        inventory: ["gloves", "hat", "socks"]
    },
    {
        name: "david",
        team: "purple",
        points: 20,
        inventory: ["scarf", "sunglasses", "socks"]
    },
    {
        name: "lisa",
        team: "yellow",
        points: 30,
        inventory: ["gloves", "umbrella", "socks"]
    },
    {
        name: "peter",
        team: "orange",
        points: 5,
        inventory: ["hat", "socks"]
    },

];

By utilizing the above player array, create a new array using forEach that adds an exclamation mark to the end of each player's name:

let modifiedArray = []
players.forEach(player => {
    let { name } = player;
    name = name + "!";
    modifiedArray.push(name);
})

console.log(modifiedArray);

I am puzzled by this code. Why did we use '{}' after 'let' in this case?

Answer №1

Exploring the concept of destructuring assignment in JavaScript allows for the unpacking of values from arrays or properties from objects, assigning them to individual variables.

Answer №2

Object deconstruction involves using { } after let in JavaScript. This technique allows for concise and efficient code writing, eliminating the need for repetitive assignment like let username = user.username;. To delve deeper into this concept, you can check out the resources available here
