   // Example application that uses charwise library

   const charwise = require('charwise');

   let str = 'example';
   console.log('Split Characters: ', charwise.splitByChar(str));
   console.log('Character at index 2: ', charwise.charAt(str, 2));
   console.log('Count of "e": ', charwise.countChar(str, 'e'));
   console.log('Reversed String: ', charwise.reverseString(str));
   console.log('Is "m" at index 2: ', charwise.isCharAt(str, 'm', 2));
   console.log('Change char "a" to upper: ', charwise.charToUpper(str, 2));
