Setting up single-player tests before adding spinner

JavaScript
305

Why are you using let? The variable doesn’t need to be changed so let is a bad way of doing it. Use const instead and define the spy on the same line.

There’s also no need to use videoPlayer.addPlayer either.

You are only being asked to add one single line to the code at https://jsfiddle.net/bx5ag2w4/5/ to define a variable, that is all. Nothing more.

Here’s the code that you ended up having at the end of the Adding tests to video player code thread:

      const coverHandler = jasmine.createSpy("coverHandler");
      manageCover.addCoverHandler(".playb", coverHandler);

It is the first line of that code which is the model you should be following.
