What would be the output? [Object Destructuring]
@Yomesh Gupta
Let say we have a variable state
which represents our current application state.
const state = {
user: {
id: null,
name: '', // empty string
subscribe: false,
link: '', // empty string
},
};
We want to destructure user
information.
function getUser() {
const {
user: {
id = 1,
name = 'Devtools Tech',
subscribe = true,
link = 'https://bit.ly/devtools-yt',
} = {},
} = state;
return {
userId: id,
name,
subscribe,
link,
};
}
Now, what would be the output if we call getUser
function.
console.log(getUser());
Option 1
{ "userId": 1, "name": "Devtools Tech", "subscribe": true, "link": "https://bit.ly/devtools-yt" }
Option 2
{ "userId": null, "name": "", "subscribe": false, "link": "" }
Option 3
{ "userId": 1, "name": "Devtools Tech", "subscribe": false, "link": "https://bit.ly/devtools-yt" }
Option 4
{ "userId": 1, "name": "", "subscribe": true, "link": "" }
