// 創建一個字符串對象，字符串對象被 JS 引擎
// 求值後，結果為'Hello, World!2013'
Handle<String> source = String::New("'hello,World!'+(2012+1)");

// 編譯字符串對象為腳本對象
Handle<Script> script = Script::Compile(source);

// 執行腳本，獲取結果
Handle <Value> result = script->Run();

// 轉換結果為字符串
String::AsciiValue ascii(result);

printf("%s\n", *ascii);
context->Exit();
}
v8::V8::Dispose();
return 0;
