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.

X : vjo.ctype()
Modify a Type 
final class R{};
 
//> final
vjo.ctype("vjo.R")

super()
 
this.base()
Call a Super Constructor with Arguments 
super(arg)

Implement an Instance Method 
void setName(String name)
 
.protos({
setName: function(String name)
Implement a Static Method 
static void setName(String name)
 
.props({
setName: function(String name)
})
Implement a Static Initializer 
{// static initialization here
static{...}
 
// static initialization here
.inits(function(){...})


Declarations

To Declare Java VJET VJO
