title: How to disable strict mode while bundling React using webpack
body: <p>Hello I am stuck with my application, my application working fine in all other browser not in IE it's throw the error </p>
  
  <pre><code>0x800a0416 - JavaScript runtime error: Multiple definitions of a property not allowed in strict mode
  </code></pre>
  
  <p>I have implemented loader in webpack.config </p>
  
  <pre><code>  module: {
      loaders: [{
          test: /\.js?$/,
          exclude: /(node_modules|bower_components)/,
          loaders: ['babel'],
          include: path.join(__dirname, 'scripts')
      }]
  }
  </code></pre>
  
  <p>and my Package.json Script contain <code>"build": "./node_modules/.bin/webpack --config webpack.config.production.js --progress --profile --colors",</code> for build the bundle </p>
  
  <p>If I will explicitly find <code>use strict</code> and remove it from bundle then it works fine so how can I remove that strict mode while create a bundle using webpack </p>
