Getting heap allocation error for a large entry size

I was trying to create an ArrayKeyMap of size 7,66,000 with each key of type
[int, string, 9 to 29 additional integers]

Implement all the Map object's methods, so this is pretty much exactly equivalent

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map

It would be neato if this had all of that, and the readme could say "It's literally exactly Map, but the keys are arrays".

Tracking:

is there a way to save the array-keyed-map as a file?

NOt an issue.
I am using array-keyed-map in my project. I would like to store my map as a JSON file. and I am writing multiple functions for different akmaps to save them to a file. I am just looking for a uniform way to store the akmap as a file.

thanks
