Deep Equal of two objects
Given two objects, determine if they are equal.
A deep equal is a process in which the entire object is compared to another object, including all nested objects and their properties.
Example
const a = { name: 'Tim', skills: ['JS', 'React'] };
const b = { name: 'Tim', skills: ['JS', 'React'] };
console.log(isEqual(a, b)); // true
