有什么方法可以获取 javascript 变量内存地址？

Question

有什么方法可以获取 JavaScript 变量的内存地址，因为在比较[1,2,3] === [1,2,3]之类的东西时，它看起来像true但它是false的，还有这个内存地址也将帮助我理解字符串的可变性和不变性

Answer 1

JavaScript itself is meant to be implementation-agnostic, so concepts like memory addresses are intentionally absent from the language itself. Outside of the language, you can use the browser's debugging tools to take a memory snapshot, and that might contain the information. Note, however, that there is no real guarantee that an object will retain its address.
