Deep merge Objects in Javascript with Mergerino

To merge objects in JS, you can use Object.assign.
The problem with is that it only accomplishes 'shallow merge'.

It does not take in account nested properties.

In my scripts I use Mergerino to get things done.

You can test it here : Merge

const merge = mergerino

const user = {
  name: 'David',
  phone: 122345678,
  location: {
    city: 'Camden',
    country: 'UK'
  }
};
const updates = {
  location: {
    city: 'Smithfield'
  }
};
console.log(Object.assign({}, user, updates));

console.log(merge(user, updates))
