JavaScript Libraries and Frameworks

JavaScript libraries help to bridge the gap between browser differences and provide easier access to complex browser features. Libraries come in two forms: general and specialty. General JavaScript libraries provide access to common browser functionality and can be used as the basis for a website or web application. Specialty libraries do only specific things and are intended to be used for only parts of a website or web application. This appendix provides an overview of these libraries and some of their functionality, along with websites that you can use as additional resources.
