Rule DetailsCopy Anchor Link

An import that binds nothing is loaded only for its side effects, which a reader cannot see. Reported: import 'm', import {} from 'm', and a require('m') whose result is discarded (an expression statement, or a non-final item of a sequence).

Not reported: any form that binds or re-exports a name (default, namespace, named, type-only, export … from, a require whose result is used, import x = require()), and specifiers listed in allowModules (exact match).
