针对JavaScript引擎在即时编译模式下的开销过高和网页加载时间过长的问题，改进JavaScript引擎中即时编译模式的编译方式，设计一种对JavaScript代码的动态编译方式，只对JavaScript代码中频繁执行的热点区域进行即时编译，其余代码则运行在解释模式下，合理地利用了即时编译模式。实验测试结果表明，动态编译方式能够减少JavaScript引擎的开销耗费，加快网页的加载速度。

Aiming at the problems of high overhead and too long time in web pages loading the JavaScript engine has in just-in-time com-pilation mode,in this paper we improve the compiling way of just-in-time compilation mode in JavaScript engine,design a dynamic compila-tion way for JavaScript code,which only compiles instantaneously the hot area frequently executed in JavaScript code,while the rest of the JavaScript codes are running in interpretation mode,thus the just-in-time compilation is properly used.Finally the experimental result shows that the dynamic compilation way can reduce the overhead of the JavaScript engine,and decreases the web pages loading time.
