jshint - Create custom warnings/rules
javascript, jshint
Solution
You should consider using ESLint in that case.
Every rule is standalone. Even the default rules. So you could take one of the default rules as a blueprint, and write your own.
Problem
Is it possible to create a custom jshint rule, add it to existing inbuilt rules, configure it (on or off) in our projects? Is jshint extendable, like how we create our own custom tasks in Grunt? Sometimes we need to enforce a javascript coding practice just in our environment. For example, we want to enforce our developers to use Date.now() instead of Date.getTime().
