Sometimes you really do just have to keep learning before it begins to make sense. I’m sure I will recognize other legitimate uses of jQuery as I continue learning.
I finally started to learn jQuery using a book titled “A Smarter Way to Learn jQuery”. It’s a very effective book, teaching in tiny two or three page chapters, hosting 20 practice exercises for each chapter online. I usually dislike practice problems and prefer to chew the meat and move on, but this latter strategy has resulted in some glaring gaps in my knowledge, and has meant the frequent rereading of chapters in books such as “C# 6.0 and the .NET 4.6 Framework”, which has been my buddy for learning C#. I can honestly say this new methodology is really effective.
Well, that’s why you have to jump in. You can find the useful bits later, but you have to understand the technology first. I’m just excited I’ve been making so much progress through these books lately.
