The difference between
node -e and
node -p is p will run the script
through the interpreter and print the results. The -e will only evaluate
the script. The time -e will print anything is if something writes to
stdout or stderr.
node -p "var a" undefined
node -e "var a" #nothing
node --prof process v8 profiler output generated
This runs the v8 profiler and generates a log of every allocation, address, and things on the stack.
Well someone is searching for this, and I'm sorry to say, it isn't a valid command :(
