Strict mode causes error in Mobile Safari - iOS 9

[coleturner]

SyntaxError: Unexpected keyword 'const'. Const declarations are not supported in strict mode.

Environment:

• Webpack 1
• Babel 6
• React v15

When compiled, this package doesn't seem to be transformed.

You may want to consider transpiling the package or adding a notice that it is not compatible with ES6->ES5 transpiled environments.

Thanks for your time!

Hi @colepatrickturner,

I haven't tested for browser-based environments but you should be able to transpile to ES5.

You can tell Webpack/Babel to ignore everything in the node_modules directory except for Object-Assign-Deep by modifying the "exclude" option:

loaders: [{
  test: /\.jsx?$/,
  exclude: /node_modules\/(?!object-assign-deep)/,
  loader: 'babel',
  query: {
    presets: ['react', 'es2015']
  }
}],

Answer found here: babel/babel-loader#171

You'll also need to ensure the Babel plugins/presets you are using includes: transform-es2015-block-scoping
