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 plugin. The final result won't contain any object literals with duplicate keys.

Example

var x = { a: 5, a: 6 };
var y = {
  get a() {},
  set a(x) {},
  a: 3
};

Out

var x = { a: 5, ["a"]: 6 };
var y = {
  get a() {},
  set a(x) {},
  ["a"]: 3
};

Installation

npm install --save-dev babel-plugin-transform-es2015-duplicate-keys
