[q] list of 'must have' options to force migration from 3rd to 4th version of lodash about eslint-plugin-lodash HOT 2 CLOSED

Hi,
Let's start with a disclaimer: the plugin is not enough to migrate Lodash versions.
It won't catch the cases of lodash functions that have ceased to exist, like _.pluck. Also, with some of the breaking changes, there's no replacement for going over the release notes and going over your code. (e.g. _.rest is a method in both versions that does completely different things).

Having said that, here are the rules that are expected to alert you upon migration (if you make sure the plugin is not configured to work with v3)

• callback-binding will report on all cases when you used thisArg for methods when it doesn't exist.
• no-extra-args: will report for all the methods that have a fixed number of arguments, if you used superfluous arguments.
• unwrap and no-double-unwrap will report on the cases where functions changed their chaining behaviour (e.g. forEach, that breaks the chain in v4 but not in v3).
• preferred-alias makes sure you use the main alias for methods, and is version dependant, so, for instance it will report when you use first instead of head.

Besides that, I'd recommend you go through the rule descriptions in the README and see which ones you'd like to enforce.
