Detailed Description

QScriptProgram retains the compiled representation of the script if possible. Thus, QScriptProgram can be used to evaluate the same script multiple times more efficiently.

 QScriptEngine engine;
 QScriptProgram program("1 + 2");
 QScriptValue result = engine.evaluate(program);
