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

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

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
