NOTE: npm < 2.7.0 does not support scoped package, but old version Node.js supports it. So when you use such older npm, you should download this package from [github.com][repo-url], and move it in node_modules/@fav/type.is-valid-date/ directory manually.
For Node.js:
`js
var isValidDate = require('@fav/type.is-valid-date');
isValidDate(new Date(2017, 8, 30)); // => true
isValidDate(new Date(9999999999, 1, 1)); // => false
isValidDate.not(new Date(2017, 8, 30)); // => false
isValidDate.not(new Date(9999999999, 1, 1)); // => true
`
Or when installing fav-type.is-valid-date from github:
`js`
var isValidDate = require('fav-type.is-valid-date');
isValidDate(new Date(2017, 8, 30)); // => true
isValidDate.not(new Date(2017, 8, 30)); // => false
