I came across an advice on an online comment which is worth sharing:
Forget about it (at least for now). Simply stick to plain old jQuery, master it, be your friend.
you suddenly find yourself getting swamped into a lot of jQuery
spaguetti code, that means that your application is getting way too
complex and your code needs some structure to make it maintainable.
is where an MVC framework can help you, by giving some logical
structure to your code, making it more modular and reusable, easier to
read and to understand.
However, it's hard to learn a solution to a problem you never had...'
This is quite like the advice that veteran programmers give - if it isn't broke, don't fix it. There is a time and place for sticking with MVC, but the traditional approach of keeping things simple is not a poor choice - especially when the code is readable.
