  • input: array
  • output: middle element(s)
    • Even number returns 2, Odd number returns 1
• flatten(...) :
  • flattening a nested array
• countLetters(...) :
  • input: sentence or string
  • output: in an object, returns a count of each of the letters
• countOnly(...) :
  • input: object listed
  • output: in an object, returns counts of input
• findKey(...) :
  • input: object and a callback
  • output: looks through the object and returns the value of the callback function
• findKeyByValue(...) :
  • input: object and a value
  • output: looks through the object and returns the first key of the given value.
    • return undefined if no key is found
• letterPositions(...) :
  • input: letterPositions('example').character
