A quick morning brain warmup. Instead of using the array method reverse, I decided to refresh my recursion skills a bit. I'm glad I did. I find this solution quite a bit more elegant (to the eyes that is). http://www.codewars.com/dojo/katas/5168bb5dfe9a00b126000018/

reversed-strings-kata-recursive.js

/* 
*  Reverse whatever string is passed into solution.
*  solution('world'); // returns 'dlrow'
*  
*/

function solution( str ) {
  
  //  Our answer
  var answer = "";
  
  // Stop recursion when we have no more string
  if( str.length == 0 ) {
    return answer;
  }
  
  // Take the last letter and recurse with the rest of the string
  answer = str.slice( -1 ) + solution( str.slice( 0, -1 ) );  
  
  return answer;
  
}
