size of undefined in bytes

[river-xd]

how much space does undefined take in the memory?..

@kakashi-69-xd when you don't define a value for a variable, it's value is undefined. So my understanding would be 0 bytes, however this StackOverflow thread considers something different: https://stackoverflow.com/questions/50854916/javascript-memory-impact-of-null-vs-undefined. This question is rather related to Google's V8 than Deno though.

Hope this helps! :)
