HtmlWebpackPlugin simplifies the creation of HTML files to serve the bundle. This is especially useful for bundles that include a hash in the filename, which changes every compilation.
When using this method, we have three choices—use a template with lodash templates, use your loader, or let the plugin generate an HTML file.

When using multiple entry points, they will be included with the <script> tags in the generated HTML.
If you have any CSS assets in Webpack's output, then these will be included with the <link> tags in the <head> element of the generated HTML. An example would be if CSS is extracted with MiniCssExtractPlugin.
