If you're getting the Error Error: EPERM: operation not permitted, open '...' , try this:

1. Empty the npm cache npm cache clean --force,
2. Delete all your folders containing compiled js/css files like rm -rf /css/style.min.css, rm -rf /js/bundle.min.js and so on.

All values are truthy except for: false, 0, "" (empty string), null, undefined, and NaN.

Confusingly, this means that the string "false", the string "0", an empty object {}, and an empty array [] are all truthy. You can double check this by passing an object into the Boolean function (e.g. Boolean("0");).
