- Once a speaker has connected, they will get to see…information about each of the connected…audience members in a table.…We will create an attendance component…to handle this task.…Let's go over to our components directory…and expand that and we're going to add this…attendance component to the parts directory.…So, I will right-click above that and select New File…and I will immediately save this file as…Attendance.js.…And we will create this component…the exact same way, first by requiring React.…
Next, by creating a variable for the component…using React.createClass.…At minimum, sending a render function…to the React.createClass function.…And then down here, on line nine,…exporting our Attendance component.…Alright, so let's go back up into our render function…and actually add the elements to this component.…So, everything is going to be stored in a div.…So, at line five here, I've added a div,…and I'll close that div down here on line seven.…
The next thing we want to do is add a header.…So, we will display the word Attendance to our speaker…
