// if you want values similar to what you'd get with real perf.now, place this towards the head of the page
// but in reality, you're just getting the delta between now() calls, so it's not terribly important where it's placed

Custom ES6 errors in Node.js

Here's how you could create custom error classes in Node.js using latest ES6 / ES2015 syntax.

os.IsExist(err) vs os.IsNotExist(err)
/*
Watch out, os.IsExist(err) != !os.IsNotExist(err)
They are error checkers, so use them only when err != nil, and you want to handle
specific errors in a different way!
Their main purpose is to wrap around OS error messages for you, so you don't have to test
for Windows/Unix/Mobile/other OS error messages for "file exists/directory exists" and
"file does not exist/directory does not exist"
