While on my last contract, I became aware (and alarmed) that I have fallen behind the curve with regard to front end technologies. I am just barely getting up to speed with MVC, and only now am getting used to products like Grunt, Bower, and Yeoman. I have had a little exposure to KnockoutJS, but there seems to be an even greater demand for AngularJS and BackboneJS.
I can claim credit for being pretty much up to date with Responsive design and Bootstrap, but there is so much else happening on the front end. Would you all advise me on the quickest/shortest route to fill in these gaps in my experience and become a taxpayer again? Thanks in advance!
