Convert Objects to Set

TODO: collapasable, copyable, download, etc

I have JS where I map over a row of results and make a collection of objects. How an I change this to a unqiue set?To change a collection of objects generated by mapping over a row of results into a unique set in JavaScript, you can use a Set. A Set in JavaScript is a data structure that only stores unique values, so it automatically eliminates duplicates. Here's how you can do it:

Assuming you have an array of objects generated by mapping over a row of results:

const results = [
  { id: 1, name: 'John' },
  { id: 2, name: 'Jane' },
  { id: 1, name: 'John' }, // Duplicate
  { id: 3, name: 'Alice' },
];

// Use a Set to store unique objects
const uniqueSet = new Set(results);

// Convert the Set back to an array if needed
const uniqueArray = [...uniqueSet];

console.log(uniqueArray);

In this example, uniqueSet will contain unique objects based on their content. The duplicates will automatically be removed. If you need the result as an array, you can convert it back from the Set using the spread operator [...uniqueSet] as shown above.
