In my blog “NuGet – Limiting updates for jQuery and Bootstrap” – we looked at continuing to utilize NuGet to keep us up to date on the latest jQuery 1.x version ( even though 2.x is out ). Reason being that we needed to stick with 1.x because we are still supporting IE 7/8. :(
So… jQuery 1.x and 2.x have feature parity – but you want to use jQuery 2.x when you can, simply because it’s a smaller download as they were able to take out a lot of IE7/8 “fixes”. Note, jQuery’s post on conditionally include one or the other based on the version of the browser.
But we also like to use the cool MVC bundling and minification feature – can we have the best of all worlds? Oh ya… :)
