Poor Mans jQuery

A lot of people use jQuery in their HTML/JavaScript applications. There’s nothing wrong with that. But I’ve seen a lot of people use jQuery only to make it easy to find elements and they are not using any of the other jQuery functions. It’s pretty clear that writing a single ‘ $ ‘ instead of the way longer usages of various function on the ‘document‘ object, like getElementById.

It most often runs in a web browser and often as a control. In many cases you need to communicate with the browser to get information about textboxes, events or details about the browser itself.
