+# babel-plugin-transform-property-literals
+
+This plugin allows Babel to transform valid identifier property key literals into identifiers.
+
+## Example
+
+**In**
+
+```javascript
+var foo = {
+  // changed
+  "bar": function () {},
+  "1": function () {},
+
+  // not changed
+  "default": 1,
+  [a]: 2,
+  foo: 1
+};
+```
+
+**Out**
+
+```javascript
+var foo = {
+  bar: function () {},
+  1: function () {},
+
+  "default": 1,
+  [a]: 2,
+  foo: 1
+};
+```
+
+## Installation
+
+```sh
+npm install babel-plugin-transform-property-literals --save-dev
+```
+
+## Usage
+
+### Via `.babelrc` (Recommended)
+
+**.babelrc**
+
+```json
+{
+  "plugins": ["transform-property-literals"]
+}
+```
+
+### Via CLI
+
+```sh
+babel --plugins transform-property-literals script.js
+```
+
+### Via Node API
+
+```javascript
+require("@babel/core").transform("code", {
+  plugins: ["transform-property-literals"]
+});
+```
