Keeping up with the latest trends in web development is tough sometimes, only because there are new things always being created. jQuery is  one of the newer creations that have come up in the last several years and its not going away. It is the most popular JavaScript library in use today. If you don’t know what jQuery is then here is a brief description: jQuery is a JavaScript Library that is fast and concise that makes HTML document traversing, event handling, animating, and Ajax interactions for rapid web development much easier. “jQuery is designed to change the way that you write JavaScript.” It’s lightweight, around 23kb, and cross browser compliant and compliant with CSS3 as well. You can create sliding banners, dropdown navigations, and much more with it. I am trying to learn more and more of it everyday, and its pretty exciting. jQuery is provided under the MIT and GPL licenses which means you can use it in your commercial projects like selling of themes and stuff. There are several good tutorials and other helpful resources on their website and I would highly recommend it and learning some yourself.
