+## Variables #1
+
+1. create "firstName" and "last_name" variables
+2. assign your values
+3. create "address" variable and assign "main street"
+   value to it
+4. re-assign address to "first street" later
+5. log all values in the console
+
+## Concatenate Strings #2
+
+1. create "street" and "country" variables
+2. assign your values
+3. create "fullMailingAddress" variable and assign
+   the result of "street + country"
+4. remember about the space
+5. log "fullMailingAddress" in the console
+
+## Numbers #3
+
+1. create "score1", "score2", "score3" variables and
+   assign values (0-100)
+2. calculate total score and average score, and assign them to the variables.
+3. log total score and average score
+4. create "plates" variable and assign 20
+5. create "people" variable and assign 7
+6. calculate remaining plates and assign to the variable
+7. add one to remaining plates
+8. create message variable and display 'There are (your value goes here) plates available' - string concatenation
+9. log message
+
+## Arrays #4
+
+1. create "fruits" array and store some fruit values
+2. setup the last item as number (random)
+3. assign first fruit to the variable
+4. re-assign last array item to the actual fruit
+5. log both first fruit variable and entire fruits array
+
+## Functions #5
+
+1. create "calculateTotal" function
+2. add two parameters subTotal, tax
+3. return sum of parameters
+4. create 3 vars "order1","order2","order3"
+5. call calculateResult, pass in some values and assign result to each order
+6. log all three orders
+7. refactor "calculateTotal" to function expression
+
+## Objects #6
+
+1. create car object
+2. add make, model, year, colors (array),
+   hybrid (boolean) keys
+3. add two methods (drive and stop)
+4. in the function body setup log with random text
+5. log make
+6. log first color
+7. invoke both methods
+
+## Conditional Statements #7
+
+1. create two objects "person1", "person2"
+2. setup name,age (15-25),
+   status ('resident', 'tourist') keys
+
+3. setup if else, condition where
+   age must be bigger than 18 and status must be
+   equal to 'resident'
+4. test with both objects
+
+## Strings #8
+
+1. create function fullName
+2. accept two parameters "firstName", "lastName"
+3. add them together (concat) and return result in uppercase
+4. invoke fullName and pass some values
+5. log result
+6. change the order of arguments
+7. refactor to object parameter
+
+## Array Methods #9
+
+Multiple Videos
+
+#### Create Students Array
+
+1. setup students array with 5 students
+   {
+   id: 1,
+   name: 'peter',
+   score: 80,
+   favoriteSubject: 'math',
+   },
+
+#### Use Multiple Files
+
+- easer to manage code base (file, project)
+- order matters
+- other ways to achieve the same result (ES6 modules, fetch DB )
+- not limited to just static data
+
+#### updatedStudents
+
+1. add role:'student' property to each object
+   using MAP method
+2. assign to 'updatedStudents' variable and log
+
+#### highScores
+
+1. filter array and return only scores >= 80
+2. assign to 'highScores' variable and log
+
+#### specificId
+
+1. find specific id in array
+2. assign to 'specificId' variable and log
+
+#### averageScore
+
+1. sum up all student.score values with reduce
+2. divide by the length of the students array
+3. assign to 'averageScore' and log
+
+#### survey
+
+1. list favorite subjects with reduce
+   {
+   english: 1
+   history: 1
+   math: 3
+   }
+2. assign to survey and log
