getHeapSpaceStatistics
Returns statistics about the V8 heap spaces, i.e. the segments which make up the V8 heap. Neither the ordering of heap spaces, nor the availability of a heap space can be guaranteed as the statistics are provided via the V8 GetHeapSpaceStatistics function and may change from one V8 version to the next.
The value returned is an array of objects containing the following properties:
[

"space_size": 2063872,
"space_used_size": 951112,
