// FP languages permit to evaluate if/else expressions as values.
// In many cases it permits to avoid using mutable variables (var/let), multiple returns, or nested ternary operators

// This is the do { } notation (stage 0), that permits to write the following right now with Babel.

const Users = ({users}) =>   (
  <div>
    {users.map(user =>
      <UserCard key={user.id} user={user}/>
