How to get last viewed scene name?

Hello, Can anyone tell me how to get the last viewed scene name within Javascript? I want to jump around between scenes using a back button. For example: I have five scenes: A, B, C, D, E. I jump to B from A. I then return to A. I jump to E from C and the return to E. Thanks for your help.
