const newUsersArray = users.filter(user => user[0] === 'S');

console.log(newUsersArray)

const users = ["Sam", "Adam", "Smith", "John", "Peter"]; const newUsersArray = users.filter((user) => user[0] === "S"); console.log(newUsersArray);

You forgot to show your array, but if you are using the one from the video, it contains objects and not simple strings. In that case, you would need to select the "name" property and then examine the first character:

const newUsersArray = users.filter(user => user.name[0] === 'S');
