##Description

The CodeGen.codeGen function takes a Script object and generates the ECMAScript string representation of it.

The generated program generally parses into a Script object that is identical to the original one with two exceptions:

• if the Script object cannot pass Validator test, the behavior of code generation is undefined.
• if there is an IfStatement without alternate-clause who is directly followed by an alternate-clause of an IfStatement, the consequent-clause of the latter IfStatement is wrapped by a BlockStatement, resulting in a slightly different parse tree.

String js = "a; b;";
Script p = Parser.parse(js);
String jsPrime = CodeGen.codeGen(p);
