Creating Variables For Destructured Objects In Addition To Their Properties

I have: const { state: { mode } } = this console.log(mode) //'mode' console.log(state) //undefined I want to declare the state variable as well. Is there a way to destructure thi

Solution 1:

Sure, just use a comma as if you were destructing another property of the parent object:

const obj = { state: { mode: 'str' }};
const { state: { mode }, state } = obj;
console.log(mode);
console.log(state);

Note that this looks very similar to, but is not the same as the following import syntax you may have seen:

importReact, { Component } from'react'

Here, the variables in brackets are named exports, while the plain variable is the default export, which is entirely different from nested objects.

Solution 2:

You can destructure the state to a variable as well:

const { state, state: { mode } } = { state: { mode: 'mode' } };

console.log(mode) // 'mode'console.log(state) // { mode: 'mode' }
