V8中的堆栈和堆(JavaScript) [英] stack and heap in V8 ( JavaScript)
问题描述
V8是否像JVM一样使用堆栈和堆?
如果是这样,它将原语放在堆栈上和堆上的对象上?
does V8 uses stack and heap like the JVM? if so does it put primitives on the stack and objects on the heap?
推荐答案
是的,V8使用堆类似于JVM和大多数其他语言。但是,这意味着将局部变量(作为一般规则)放在堆栈中的对象和堆中的对象上。例如,如果函数关闭这些值,则这可能不成立。
与在JVM中一样,如果基元存储在局部变量中,它们只能存储在堆栈中。
Yes, V8 uses a heap similar to JVM and most other languages. This, however, means that local variables (as a general rule) are put on the stack and objects in the heap. This may for instance not hold if a function closes over these values. As in the JVM, primitives can only be stored on the stack if they are stored in a local variable.
作为用户,它不是你想要的东西通常需要担心。
As a user it is not something you would normally need to worry about.
