I am currently trying to compare the TodoMVC Examples of Angular, Ember, Backbone and Knockout with the help of code metrics. After some research, I found jsmeter.info and jscomplexity.org which both cover the metrics i would like to compare. (Lines of Code, Cyclomatic Complexity, Halstead Metrics, Maintainability Index)
My problem here is that I have to analyze every file on it's own and I couldn't manage to find out how I can aggregate the outputs of the different files, that there is just one result at the end for every implementation of TodoMVC.
So for Lines of Code it's easy, I just have to add them, but I'm pretty sure that this is not applicable for the other metrics. Do I have to take the average or is there a better way to find a meaningful result?
Thank you in advance.
