  restrictedIdentifiers: {
    deny: ["cb", "val"],

const val = fetchUsers();

function cb() {}

function process(val, cb) {}

import val from "lib";

const users = fetchUsers();

function onComplete() {}

function process(users, onComplete) {}

import data from "lib";

When Not To Use It

This rule is only relevant for projects that have established conventions of names that should not be used. If you’re not particular about banning specific identifier names, you likely don’t need this rule.
