Documentation for VJET JavaScript IDE is available in 2 forms:
+
The following tables summarize the semantic similarities between Java and VjO.
−
* [[#Wiki Documents]] <nowiki>-</nowiki> Informational and referential documentation; located on the VJET open source site.
+
−
* [[VJET:Overview#CheatSheets|Eclipse Cheat Sheets, Samples, and Help]] <nowiki>-</nowiki> Tutorial and task related topics available in Eclipse
+
  
−
Since VJET JavaScript IDE is an Eclipse plugin, most of the documentation will be in Eclipse.&nbsp; With Eclipse Cheat Sheets, you can view documentation, step through tutorials, and code at the same time.

The following tables summarize the semantic similarities between Java and VjO.

Semantic Java VJET VJO
Declare a Namespace package vjo.x.y 


vjo.ctype("vjo.x.y.Z") // where Z is the name of a class.

|- | Import a Class | import vjo.utils.X | 

.needs("vjo.utils.X")


Type Definitions and Manipulation

Semantic Java VJET VJO
