| Mar 3, 2023 at 17:39 | comment | added | Gerard ONeill | Your middle paragraph implies that "IF (x in obj)" is good for checking the prototype chain, but your second to last paragraph implies that it checks the chain and is faster. So is "syntax" the only reason to use (x in obj)? | |

Active reading [<https://en.wikipedia.org/wiki/Node.js>]. Removed meta information (this belongs in comments). Limited the output to three signicant figures (more are definitely not warranted) and converted to a single number (seconds).
