This is a great way to use existing data. You could also use the reduce function
return messageData.reduce((totalLikes, message) => {
// If messages.liked is true add 1 to totalLikes, else add 0
return (totalLikes += message.liked ? 1 : 0);
}, 0); // The 0 here sets the initial value of totalLikes to 0| <header> | ||

You could just call your function in jsx like {countLikes(chatMessageData} and in Learn you were getting an error message because of the style of heart you are using. You can alter the tests to accept the heart you want to use.
