const { foo: [bar], bar: [{ baz: foo }] } = { foo: [1], bar: [{ baz: 3 }] } console.log(bar) console.log(foo) //

In this code, object destructuring with nested arrays and objects occurs:

const { foo: [bar], bar: [{ baz: foo }] } = { foo: [1], bar: [{ baz: 3 }] }

console.log(bar) // 1
console.log(foo) // 3

Explanation:

• foo: [bar] — from the foo property, which is an array [1], the first element is taken and assigned to the variable bar.
• bar: [{ baz: foo }] — from the bar property, which is an array with one object { baz: 3 }, the baz field is taken and assigned to the variable foo.

As a result, bar equals 1, and foo equals 3.

Output:

1
3
