Dynamic programming language(动态编程语言)

动态编程语言是指可在运行阶段时执行那些在编译阶段执行的操作的编程语言。比如,在 JavaScript 中, 我们可以在程序运行时改变变量的类型,或者为一个对象增加一个新属性或者方法。

这正好与静态编程语言相反,在静态编程语言的运行阶段,一般是无法执行这些改变的。

Note that while there is indeed a connection between this dynamic/static property of programming languages and dynamic/static-typing, the two are far from synonymous.
