noop

The standalone lodash.noop package as a vendorable file. Useful when you want a named no-op helper without adding a dependency.

Why copy this?

This page ships the published lodash.noop file in both raw and normalized forms. The value is to preserve a familiar tiny helper locally when existing code already expects it.

Native alternative: An empty arrow function is trivial to write, but vendoring the known helper can still be useful when replacing an existing dependency.

Note: Raw and normalized views are both available. Use normalized when you want an ESM and TypeScript-friendly file, and raw when you want the original published package shape.

This copy is your responsibility once you adopt it. It does not automatically receive upstream bug fixes or security updates.

Variant note: Rule-based normalization for modern TS projects. The goal is easier import and build compatibility, not changed behavior.

Transforms: module.exports-to-export-default, js-extension-to-ts-extension

Validation: This normalized variant is intended to stay oxlint and oxfmt clean in this repo.
