+# babel-plugin-minify-builtins
+
+Minify Standard built-in Objects
+
+## Example
+
+**In**
+
+```javascript
+Math.floor(a) + Math.floor(b)
+```
+
+**Out**
+
+```javascript
+var _Mathfloor = Math.floor;
+
+_Mathfloor(a) + _Mathfloor(b);
+```
+
+## Installation
+
+```sh
+npm install babel-plugin-minify-builtins --save-dev
+```
+
+## Usage
+
+### Via `.babelrc` (Recommended)
+
+**.babelrc**
+
+```json
+{
+  "plugins": ["minify-builtins"]
+}
+```
+
+### Via CLI
+
+```sh
+babel --plugins minify-builtins script.js
+```
+
+### Via Node API
+
+```javascript
+require("@babel/core").transform("code", {
+  plugins: ["minify-builtins"]
+});
+```
+
+## Options
+
++ `tdz` - Account for TDZ (Temporal Dead Zone)
