# babel-plugin-transform-strict-mode

> This plugin places a `"use strict";` directive at the top of all files to enable [strict mode](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Strict_mode).

This plugin may be enabled via `babel-plugin-transform-es2015-modules-commonjs`.
If you wish to disable it you can either turn `strict` off or pass
`strictMode: false` as an option to the commonjs transform.

## Example

**In**

```javascript
foo();
```

**Out**

```javascript
"use strict";

foo();
```

## Installation

```sh
npm install --save-dev babel-plugin-transform-strict-mode
```
