Being a Rails developer since 2009 I've noticed how much I needed to use the frameworks helper feature. And often, a big part of the work I did in the helper modules was for doing simple text manipulation to display in the views.
In Rails, helpers are not exactly fast and if you can reduce the number of processing you do them or eventually the number of helper files you have you can reduce the burden in the back-end. Also, web browsers today are optimized enough for us to transfer some processing to the front-end side.
So, this is basically it, transfering some computation from the server to the browser and helping your web server deliver the response in some faster way.
