Destructuring Objects

Share This Post

Just like in destructuring arrays, we can also destructure objects. The syntax is slightly different using curly braces.

let animal = { id: 1, kind: ‘gorilla’ }; 
let id, kind; ({ id, kind } = animal);  console.log(id, kind);

The output would be 1 and ‘gorilla’.

Notice the parentheses. We did not have those in the destructuring arrays lesson. The reason we need to put it in parentheses is due to scope. Since JavaScript uses curly braces for code blocks, it gets confuses without the parentheses, because it doesn’t know whether you are destructuring or defining a code block. The parentheses clears this up.

Happy Coding!
