id-blacklist

This is the old name for id-denylist. It takes the same options. Use id-denylist in new configs.

Names like data, tmp or cb don't say much about what they hold. The rule reports the names you list when they name a variable, parameter, function, class, import, object key or class member, or a property you assign to. Without a list, it reports nothing.

Examples

[lint.rules]
id-blacklist = ["error", "data", "callback"]

Reported:

const data = loadUser(id);

function save(user, callback) {}

const response = { data: 1 };
response.data = 2;

Not reported:

const user = loadUser(id);

function save(user, onSaved) {}

console.log(response.data);

Unlike id-denylist, this rule doesn't look at private names:

class Store {
  #data = new Map();
}

Options

Each option is a name to disallow. Names are compared exactly, so "data" doesn't match userData.
