Question:
I am involved in a project that requires the client-side embedded scripts to be compatible down to version 3 of Internet Explorer and Netscape Navigator. So far I have been unsuccessful in finding documentation or detailed comparisons on which objects/methods/properties are supported. Any suggestions would be greatly appreciated.
Answer:
The best JavaScript reference I’ve found is JavaScript, The Definitive Guide by David Flanagan, ISBN 1565923928. Although this book is not really a learning tool, it is an excellent resource and provides a wealth of compatibility information.
