Remove 'use strict' if the file is 'not strict'

Most of the bundlers and transpilers such as babel add `'use strict'` to the above of your file. This plugin will remove them if you add `'not strict'` to that file. You can also use this plugin to remove `'use strict'` from all the files

## Installation

```

npm install --save-dev babel-plugin-transform-not-strict

```

You should also install the peer dependencies:

```

npm install -save-dev "@babel/core"

```

## Usage

1. put the following in above the a file that is not strict:

```js

"not strict";

```

2. Add `"babel-plugin-transform-not-strict"` to the list of your babel plugins.

For example, create a `babel.config.js` file at the root of the project with the following content:

```js

let presets = [];

let plugins = ["babel-plugin-transform-not-strict"];

module.exports = {

  presets: presets,

  plugins: plugins,

  exclude: "node_modules/**",

  sourceMap: "inline",

};

```

### Usage Remove All

You can also use this plugin to remove `'use strict'` from all the files. Just pass `removeAll: true`.

```js

let presets = [];

let plugins = [

  [

    "babel-plugin-transform-not-strict",

    {

      removeAll: true,

    },

  ],

];

module.exports = {

  presets: presets,

  plugins: plugins,

  exclude: "node_modules/**",

  sourceMap: "inline",

};

```

### Usage Extra Directive or Comment Triggers

You can add more directive or comment triggers for removal of `'use strict'`. In the following example, `'use babel'` directive or comments that include `'@babel'` or `'@flow'` also instruct the plugin to become active and remove `'use strict'`

```js

let presets = [];

let plugins = [

  [

    "babel-plugin-transform-not-strict",

    {

      directiveTriggers: ["use babel"],

      commentTriggers: ["@babel", "@flow", "* @babel", "* @flow"],

    },

  ],

];

module.exports = {

  presets: presets,

  plugins: plugins,

  exclude: "node_modules/**",

  sourceMap: "inline",

};

```
