Current behavior
If an empty array [] is supplied to the show method of the <Messages /> component it will crash.

I have found the issue and the solution as well. The reason it is crashing is because newMessages within the show method is not assigned (only declared) which makes the value undefined. When the component then later tries to iterate this.state.messages its undefined which is why its crashing. Simply declaring it like this will solve the issue: let newMessages = [];

I will submit a PR for this.

Expected behavior
I expect it not to crash but instead not show any messages.
