Describe two differences between jQuery 1.x and jQuery 2.x?.
What will be an ideal response?
The first, jQuery 1.x, is backward compatible with Internet Explorer version 6 and later, meaning that it supports IE 6, 7, and 8. By contrast, jQuery 2.x does not support these older versions of IE, but instead supports only IE 9 and later. Because it requires less extra code for these older browsers, the jQuery 2.x library is slightly smaller than jQuery 1.x. This size difference can be significant when developing a complex web app.
