Module 2 Assessment

Sales Team

You are managing a sales team and you are interested is analyzing some data related to their age and total sales. Take a moment to review the following data structure you will be analyzing:

var salesTeam = [{name: {first: 'Aleen', last: 'Atkins'}, age: 26, sales: '$2314'},
 		{name: {first: 'Alvaro', last: 'Angelos'}, age: 55, sales: '$1668'},
 		{name: {first: 'Denese', last: 'Dossett'}, age: 29, sales: '$9248'},
 		{name: {first: 'Douglas', last: 'Denney'}, age: 53, sales: '$5058'},
 		{name: {first: 'Earline', last: 'Erickson'}, age: 19, sales: '$18876'},
 		{name: {first: 'Herman', last: 'Hazell'}, age: 25, sales: '$2746'},
 		{name: {first: 'Homer', last: 'Hirth'}, age: 26, sales: '$474'},
 		{name: {first: 'Hwa', last: 'Heidt'}, age: 53, sales: '$9607'},
 		{name: {first: 'Hyon', last: 'Hampshire'}, age: 46, sales: '$13598'},
 		{name: {first: 'Issac', last: 'Ingerson'}, age: 45, sales: '$5225'},
 		{name: {first: 'Jeraldine', last: 'Joplin'}, age: 39, sales: '$2891'},
 		{name: {first: 'Jin', last: 'Jeffrey'}, age: 17, sales: '$14402'},
 		{name: {first: 'Joleen', last: 'Jolin'}, age: 45, sales: '$15736'},
 		{name: {first: 'Jude', last: 'Jarrett'}, age: 53, sales: '$7557'},
 		{name: {first: 'Magda', last: 'Mireles'}, age: 18, sales: '$1498'},
 		{name: {first: 'Mistie', last: 'Montealegre'}, age: 31, sales: '$6920'},
 		{name: {first: 'Nancy', last: 'Napoli'}, age: 49, sales: '$5255'},
 		{name: {first: 'Regine', last: 'Rohrbaugh'}, age: 33, sales: '$7881'},
 		{name: {first: 'Rolando', last: 'Riebel'}, age: 35, sales: '$8573'},
 		{name: {first: 'Scarlett', last: 'Stagg'}, age: 36, sales: '$7126'},
 		{name: {first: 'Sherron', last: 'Strawn'}, age: 36, sales: '$8848'},
 		{name: {first: 'Susan', last: 'Shilling'}, age: 29, sales: '$8542'},
 		{name: {first: 'Tama', last: 'Tworek'}, age: 16, sales: '$9200'},
 		{name: {first: 'Tonisha', last: 'Taunton'}, age: 41, sales: '$5219'},
 		{name: {first: 'Vergie', last: 'Villescas'}, age: 25, sales: '$8712'}];

Part 1

Write a function, isTeenager, that takes in an array of information, salesTeam, and returns an array that lists the full names of each member of the sales team that is a teenager. Make sure the first and last names are separated by a space.

function isTeenager(salesTeam) {

}

Part 2

Copy/paste in the following assertObjectsEqual function and its invocation. If you confirm that isTeenager passes the test, move to Part 3. If you are receiving an error message, correct your isTeenager function.

function assertObjectsEqual(actual, expected, testName) {
  if (JSON.stringify(actual) === JSON.stringify(expected)) {
    console.log('Test passed');
  } else {
    console.log('Test ['+testName+'] failed: expected ', expected, ' but got, ', actual );
    }
}

assertObjectsEqual(isTeenager(salesTeam), ["Earline Erickson", "Jin Jeffrey", "Magda Mireles", "Tama Tworek"], "Should return a list of all teenagers on the Sales Team");

Part 3

Write a function, oldest, that takes in an array of information, salesTeam, and returns a sentence with the person's first and last name, e.g. "The oldest student is Tina Fey". If there is a tie for the oldest student, return the student whose name appears first in the salesTeam array.

Start this part by writing a single invocation of the assertObjectsEqual function before you write the body of the oldest function. Once you complete writing the body of oldest you should see your test pass.

Note: Even though we are returning a string, not an object, assertObjectsEqual will still work as our test since we're using JSON.stringify(). An interesting read (whenever you finish this assessment) is this question and answer on StackOverflow.

Part 4

Write a function, tenThousandClub, that takes in an array of information, salesTeam, and returns an array that lists the full names of each member of the sales team that is has sales greater than $10,000. Make sure the first and last names are separated by a space.

As with Part 3, start this part by writing a single invocation of the assertObjectsEqual function before you write the body of the tenThousandClub function. Once you complete writing the body of tenThousandClub you should see your test pass.

Hint: I recommend you write a helper function, salesToNumber, that converts the sales string to a number. Feel free to look up parseInt() and slice() on MDN if you don't remember how they work.
