# 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
```
## Usage
