Wait what.. ends with: "So now the JS library listens on the special classes and acts accordingly. This as opposed to what we had earlier is that now for N number of times we work with data from the backend the JS code responsible for it is the same. So for instance if you compare JQuery to Bootstrap. whereas you write some amount of JS to use J [cut-off]". Surely this is just re-factored JS then?!
