I created an array of unique createdAt values from an users array. Then I mapped this table and added to it every user that has the same creation date
function App() {
let users = [
{name: 'user1', createdAt: 'November'},
{name: 'user5', createdAt: 'November'},
{name: 'user2', createdAt: 'April'}];
let rows = [...new Set(users.map(item => item.createdAt))];
return (
<div className="App">
{rows.map(i=><div>
<h1>{i}</h1>
<ol>{users.map(j => i === j.createdAt ? <li>{j.name}</li>: null)}</ol>
</div>)}
</div>
);
}

You may want to create some form of 'groupBy' function in order to achieve this. Have a look at this example.
const users = [{
firstName: "Garnet",
createdAt: "January"
},
{
firstName: "Pearl",
createdAt: "February"
},
{
firstName: "Amethyst",
createdAt: "January"
},
{
firstName: "Steven",
createdAt: "March"
}
]
function groupBy(array, key) {
return array.reduce((acc, obj) => {
const property = obj[key]
acc[property] = acc[property] || []
acc[property].push(obj)
return acc
}, {})
}
console.log(groupBy(users, 'createdAt'))
