JS - Destructuring Array of Objects

destructuring_array_of_objects.js

let a = [{grape: 1}, {orange: 2}, {peach: 3}];
let b = {};

// turn b into {grape: 1, orange:2, peach: 3}
a.forEach((el, i) => {
	b[Object.keys(a[i])] = el[Object.keys(el)[0]]
})

// using object destructuring syntax
let [{grape}, {orange}, {peach}] = a;

// destructuring array of objects with default values
// getting first element
const arr = [{
	formSchema: { name: 'Ana'}
}];
const [{formSchema = {}}] = [] = arr;
