T> Note that the `--optimize-minimize` flag enables tree shaking by including the `UglifyJsPlugin` behind the scenes. Alternatively, the `UglifyJsPlugin` can be included manually in the `plugins` section of your configuration file. The plugin, combined with webpack's resolving of `import` and `export` statements, is what makes tree shaking possible. See the [production build](/guides/production) guide for more information.
