  • assertObjectssEqual(obj1,obj2): asserts if two objects are equal
  • countLetters(string): count the number of times each letter appears in a string
  • countOnly(allItem,itemsToCount): given an array of items, the function will only count certain items which are indicated by the itemsToCount object.
  • eqArrays(arry1,arry2): compares two arrays and returns Boolean
  • eqObjects(ob1,obj2): compares two Objects and returns Boolean
  • findKey(obj,callback): returns the first key of an object that statisfies the callback function.
  • findKeyByValues(obj,value): returns the key whose value is equal to the given value.
  • head(arry): returns the first element of an array
  • letterPositions(string): returns an the indexes at which each letter appear.
  • map(arry,callback): maps an array.
