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

• 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.
