Deconstruct the original data

Sometimes an object contains many attributes, and we only need a few of them. Here we can use deconstruction to extract the attributes we need. For example, a user object is as follows:

Const rawUser = {name: 'John', surname:' Doe', email: 'john@doe.com', displayName:' SuperCoolJohn', joined: '2016-05-05, image:' path-to-the-image', followers: 45.}

We need to extract two parts, the user and the user information, and we can do this:

Let user = {}, userDetails = {}; ({name: user.name, surname: user.surname,... userDetails} = rawUser); console.log (user); / / outputs {name: "John", surname: "Doe"} console.log (userDetails) / / outputs {email: "john@doe.com", displayName: "SuperCoolJohn", joined: "2016-05-05", image: "path-to-the-image", followers: 45} Thank you for reading this article carefully.
