How to extend the response of an api in react by adding a new property based on a condition?

I want to call an API and extend the response by adding a new ‘category’ prop to each
categories [‘thirds’, ‘fifths’, ‘magic’]

• if the id is divisible by 3 => thirds
• if the id is divisible by 5 => fifths
• if the id is divisibly by 3 and 5 => magic

The url is https://jsonplaceholder.typicode.com/posts

How do i do that?

async function getData() {
    const response = await fetch("https://jsonplaceholder.typicode.com/posts");
    const data = await response.json();
  }

{contacts.map((contact) => (
             {contact.id}
              {contact.userId}
            {contact.title}
              {contact.body}
           
            ))}
