Javascript: Assign values to already declared variables using destructuring

A lot of time we get this requirement to assign a variable to a new value which we get from an Array or Object.

Here is the common way to do it:

let platform = "twitter";
let followersCount = 122;
let updated_social_data = {
  social_platform: "instagram",
  followers_count: 452
};
platform = updated_social_data.social_platform;
followersCount = updated_social_data.followers_count;

But with the ES6 destructuring you can do it in below manner.

updated_social_data = { social_platform: "twitter", followers_count: 3456 };
({ social_platform: platform, followers_count: followersCount } = updated_social_data);

You can also apply this for Array Destructuring too
