+# @babel/plugin-transform-duplicate-keys
+
+> 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.
+
+## Example
+
+**In**
+
+```javascript
+var x = { a: 5, a: 6 };
+var y = {
+  get a() {},
+  set a(x) {},
+  a: 3
+};
+```
+
+**Out**
+
+```javascript
+var x = { a: 5, ["a"]: 6 };
+var y = {
+  get a() {},
+  set a(x) {},
+  ["a"]: 3
+};
+```
+
+## Installation
+
+```sh
+npm install --save-dev @babel/plugin-transform-duplicate-keys
+```
+
+## Usage
+
+### Via `.babelrc` (Recommended)
+
+**.babelrc**
+
+```json
+{
+  "plugins": ["@babel/plugin-transform-duplicate-keys"]
+}
+```
+
+### Via CLI
+
+```sh
+babel --plugins @babel/plugin-transform-duplicate-keys script.js
+```
+
+### Via Node API
+
+```javascript
+require("@babel/core").transform("code", {
+  plugins: ["@babel/plugin-transform-duplicate-keys"]
+});
+```
