Say we have a prop.users of the shape:
const users = [
{username: 'bob', age: 30, tags: [{name: 'work', id: 1}, {name: 'boring', id: 2}]},
{username: 'jim', age: 25, tags: [{name: 'home', id: 3}, {name: 'fun', id: 4}]},
{username: 'jane', age: 30, tags: [{name: 'vacation', id: 5}, {name: 'fun', id: 4}]}
];
