  # babel-plugin-transform-es2015-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 [transform-es2015-computed-properties](http://babeljs.io/docs/plugins/transform-es2015-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-es2015-duplicate-keys
  ```
  
  ## Usage
  
  ### Via `.babelrc` (Recommended)
  
  **.babelrc**
  
  ```json
  {
    "plugins": ["transform-es2015-duplicate-keys"]
  }
  ```
  
  ### Via CLI
  
  ```sh
  babel --plugins transform-es2015-duplicate-keys script.js
  ```
  
  ### Via Node API

  require("babel-core").transform("code", {
    plugins: ["transform-es2015-duplicate-keys"]
