This is the official guide to building native JavaScript applications for Palm's new mobile operating system, Palm® webOS™. Written by Palm's software chief technology officer along with the Palm webOS development team, Palm webOS provides a complete tutorial on the design principles, architecture, UI, tools, and services necessary to develop webOS applications-including the Mojo JavaScript framework and Palm's SDK.
