Examples

Initialisation:

var ClientFeatures = require('client-features');

window.features = new ClientFeatures({

  landingPage: {
    type:       'ga-experiment',
    experiment: 'XXXXXX',
    variants:   ['original', 'red', 'green']
  },

  actionToolbar: true,

  // Do a thing
}

switch (window.features.landingPage) {
  case 'red':
    // ????
    break;
  case 'green':
    // ????
    break;
  case 'original':
  default:
    // ????
}
