How to remove duplicates in an array using JS Set?

Consider we have an simple string array with duplicate values,

const authorNames = [
  'Param',
  'Moises',
  'Fernando',
  'Joshua',
  'Param',
  'Joshua'
];

The array have Param and Joshua values duplicated twice. There are several ways to remove duplicates, using Set is just one among them.

const uniqueAuthorNames = [...new Set(authorNames)];
console.log(uniqueAuthorNames); // Output - ["Param", "Moises", "Fernando", "Joshua"] ✅

What if the data is an array of objects?

We can make it work, but directly using Set on the array of objects won't work.

const authors = [
  {
    name: 'Param',
    age: 30
  },
  {
    name: 'Joshua',
    age: 26
  },
  {
    name: 'Param',
    age: 30
  }
];
const uniqueAuthors = [...new Set(authors)];
console.log(uniqueAuthors); // Output - It won't remove the duplicates ❌
