 Always provide types and defaults for all documented options to keep the documentation clear and accessible. Types and defaults should be added after introducing the option.
 
+Webpack configuration defaults can vary depending on the selected mode. The two used are `development` and `production`, and each applies different default optimizations.
+
+#### Development mode defaults
+
+- Optimized for debugging
+- Includes useful warnings and error messages
+- Output is readable and not minified
+- Faster incremental builds
+
+#### Production mode defaults
+
+- Optimized for performance
+- Output is minified and optimized
+- Removes unnecessary code (e.g. dead code elimination)
+- Smaller bundle size

+#### Example
+
+```js
+module.exports = {
