Next Steps
This article has provided a very short introduction to the rich world of the jQuery library, hopefully persuading you to take a deeper look into it. Thousands of web developers have already made that step; some of them have extended jQuery with numerous plug-ins and made those plug-ins readily available. For example, the jQuery UI plug-in provides an easy-to-use API supporting several modern user-interface paradigms (for example, object resizing and drag-and-drop support). The jQuery plug-in repository provides access to hundreds of user-developed plug-ins addressing almost any need.
If you've decided to switch from your current JavaScript library to jQuery, do yourself a favor: Don't rush to Google.com to find the specific code example you need. Buy two jQuery books (an introduction and a reference), take a few hours to read them, and keep them handy. Long term, this will be the best investment of your time and money.
