+`unique` is a strategy used for forcing uniqueness within configuration. It's most useful with plugins when you want to make sure there's only one in place.

+The first `<field>` is the config property to look through for duplicates.

+`<fields>` represents the values that should be unique when you run the field => field function on each duplicate.

+const { mergeWithCustomize, unique } = require("webpack-merge");
+
+const output = mergeWithCustomize({
+  customizeArray: unique(
+    "plugins",

 ## **`mergeWithRules`**
 
 To support advanced merging needs (i.e. merging within loaders), `mergeWithRules` includes additional syntax that allows you to match fields and apply strategies to match. Consider the full example below:

 The way it works is that you should annotate fields to match using `match` (or `CustomizeRule.Match` if you are using TypeScript) matching your configuration structure and then use specific strategies to define how particular fields should be transformed.
