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