# babel-plugin-transform-block-scope-to-iife

Replaces brackets used as scope in a file by an IIFE.   

This prevents exposing variables in `window` when `const` or `let` are transformed to `var` after transpiling to ES5.

**Input:**

```js

{

  const { Element } = Polymer;

}

```

**Output:**

```js

(function () {

  const {

    Element

  } = Polymer;

})();

```

## Install 

```

npm i babel-plugin-transform-block-scope-to-iife

```

## Usage 

### With a configuration file (`.babelrc`)

```json

{

  "plugins": [

    ["babel-plugin-transform-block-scope-to-iife"]

  ]

}

```

### Via Node API

```js

require("@babel/core").transform("code", {

  plugins: ["babel-plugin-transform-block-scope-to-iife"],

});

```
