Prefer _.includes

When comparing the index of an item/substring with an indexOf method, it can be more expressive to use _.includes

Rule Details

This rule takes one argument - an options object, with the property includeNative. If true, the rule will report on all indexOf calls, and if false, it will only report on _.indexOf calls.

The following patterns are considered warnings:

var a = _.indexOf(b, c) === -1

/*eslint lodash/chain-style: [2, {"includeNative": true}]*/
if (a.indexOf(b) === -1) {
 // ...
}

The following patterns are not considered warnings:

x = _.indexOf(a, b);

if (_.includes(a, b)) {
 // ...
}

When Not To Use It

If you do not want to enforce using _.includes, you should not use this rule.
