JsWizzi is a subset of the ECMA-262 javascript standard used by the wizzi factory for processing ittf documents and build mTrees.JsWizzi uses the quite efficent esprima parserand is run by a custom javascript engine (JsWizziRunner).

Ittf documents may contain Js-Wizzi statements in

• The value part of nodes (ittf node values are interpolated)

  
                              
     1 caption ${ name.capitalize() }
                              

• Conditional expression of $if, $elif, $while command nodes

  
                              
     1 $if name.substring(1,2) === 'is'
                              

• Collection name of $foreach command node

  
                              
     1 $foreach item in model.getCollection('alfa')
                              

• Body of $ and $global command nodes

  
                              
     1 $ var beta = 100
                              

                    
   1 ul
   2   $ var i = 0;
   3   $while i < 10
   4     li counting ${i}
   5     $ i++;
                    

The esprima syntax tree format is expected to be compatible with the Mozilla SpiderMonkey Parser API.
