 # @babel/plugin-transform-duplicate-keys
 
-> Compile objects with duplicate keys to valid strict ES5.
+> Compile objects with duplicate keys to valid strict ES5
 
-This plugin actually converts duplicate keys in objects to be computed properties, which then must be handled by the [@babel/plugin-transform-computed-properties](http://babeljs.io/docs/plugins/transform-computed-properties) plugin. The final result won't contain any object literals with duplicate keys.
+See our website [@babel/plugin-transform-duplicate-keys](https://new.babeljs.io/docs/en/next/babel-plugin-transform-duplicate-keys.html) for more information.
