How to make a React component out of this function?

Question

React

There are 2 functions, should these functions be made a React component? And in general, if there is an intelligent React developer here, I can give a link to an open-source project, I don’t need a big code review. Thanks

// processMessage function is called when the chat service sends a message.
// jQuery object with the response and insert message after converstaion.
function processMessage(username, data) {
    $('<span class="message">' + '[' + getCurrentTime() + '] ' + '<strong>' + username + ':</strong> ' + data + '</span><br/>').insertAfter($('#conversation'));
}

// updateUserList function is called when server sends an updated user list.
function updateUserList(data) {
    $('#users').empty();
    $.each(data, function(key, value) {
        $('#users').append('<div class="username"><i class="fa fa-user" aria-hidden="true"></i> ' + key + '</div>');
    });
}
