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
In
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
};
