• countOnly(allItemsArray, itemsToCountObject): This function returns an object with the counts of each name it found in the array that was marked true to count in the itemsToCountObject.

  • allArrayItems: const firstNames = [ "Karl", "Salima", "Agouhanna", "Fang", "Kavith", "Jason", "Salima", "Fang", "Joe" ];
  • itemsToCountObject: {"Jason": true, "Karima": true, "Fang": true, "Agouhanna": false}.

• eqArrays(array1, array2): This function returns true if two arrays are the same, and returns false if two arrays are not the same.

• eqObjects(object1, object2): This function returns true if two objects are the same, and returns false if two objects are not the same.

• findKeys(object, callback): This function returns the key if it exists specified by the callback function passing a value to it.

• findKeysByValue(object, value): This function returns the key specified by the value passed to it.

• index.js: This file exports every function as one object.

• letterPositions(sentence): This function returns an object with the indexes of each letter. Example -> letterPositions('hello') would return { h: 0, e: 1, l: [2, 3], o: 4}

• map(array, callback): This function returns an array where every element of the passed array has been altered by a callback function. Does not alter original array.
