Lab 14.2 error?

andrewpartrickmiller

'use strict'
setTimeout(() => {
  console.log() // TODO output uptime of process
  console.log() // TODO output uptime of OS
  console.log() // TODO output total system memory
  console.log() // TODO output total process memory
}, 1000)

for this exercise this particular line:

console.log() // TODO output total process memory

throws an assertion error when I log

process.memoryUsage().rss

Although it works when I use.

process.memoryUsage().heapTotal

My understanding is that the heapTotal is not the total process memory.
I think that the rss includes heapTotal and external memory for both the V8 and c++ memory usage. While heapTotal only represents V8 memory usage.

Am I wrong or is there an error in the test?

hey @andrewpartrickmiller you're not wrong - I was using process in a slightly different (less correct) way to refer to just the JS portion. I've improved the wording by changing the word "process" to "heap". Thanks for the feedback Andrew!
