I think the project was a good difficulty. I had to check the docs a few times, but never got too stuck. It took me about 2 hours to complete. The project is here: https://github.com/stuffundefined/mixed-messages
It was good to see how you solved this. I also found a way around having two of the same message but used a loop to check an array holding the random choices to see if the choice had already been generated. If not then I added the choice to an array and then used the array to select the message.
A post was split to a new topic: My Positive Mixed Messages Project
Cool solution! Good use of the loop
