from camelcase.

For those who have encountered the same problem while supporting older versions of browsers using Babel and Webpack, you should add this package to the rule for parsing it with Babel

{

  exclude: /node_modules\/(?!camelcase)/,
  use: [
    { loader: 'babel-loader' },
  ],
},

from camelcase.
