OBSOLETE?

No one has a crystal ball when it comes to what technologies will be broadly available or used in 5 years, but Dojo attempts to provide APIs that are generic enough to be (directly) useful with today's capabilities while still building in room for future improvement. The dojo.io.bind() interface is a great example of this principle: when first written it wrapped only a single Transport class, but now provides a normalized interface to many ways of receiving and sending data from JavaScript enabled environments.
