// 		Part 1

// Let's start with pretty-ing up our data a little bit. Looks like we forgot to capitalize the first and last names of our employees when we entered them into our system.

// Write a function capitalize that takes in the salesTeam array and modifies it so that the first letter of the first and last names are capitalized.

// Note: this function does not have a return value, it only modifies the passed it argument.

// function capitalize(salesTeam) {
//   // your code here

// }
// Testing

// Tests will use a different team with the exact same data structure
// No other input values will be tested
// Tests will check if your function has a proper return value
// Tests will check to make sure you used an appropriate higher order function


function capitalize(salesTeam) {
  //input: array of objects
  //output: same
  // asking us to capitalize first letter of the first and last names
  //1st level = array, next = objects, = name props;
  salesTeam.forEach(function (member) {
    member.name.first = member.name.first[0].toUpperCase()+member.name.first.slice(1);
    member.name.last = member.name.last[0].toUpperCase()+member.name.last.slice(1);
  });
  return salesTeam;
}
//console.log(capitalize(salesTeam));
//******************Part 2********
//Using the below assert function, write a simple test that checks one of the elements of the salesTeam array to make sure capitalize did its job.
function assert(expectedBehavior, descriptionOfCorrectBehavior) {
  if (!expectedBehavior) {
    console.log(descriptionOfCorrectBehavior);
  } else {
    console.log('test passed');
  }
}

//Edit the below invocation of the below assert function to use JSON.stringify() where necessary to test your capitalize function.

// capitalize(salesTeam);
// assert(JSON.stringify(salesTeam[2].name) === JSON.stringify({first: 'Denese', last: 'Dossett'}), 'should capitalize the first letter of the first and last names');
//***************************Part 3******************************

// We are interested in knowing how our team is generally performing. Write a function averageTeamSales that takes in the salesTeam array and returns a single number, the average of all sales for the team. Make sure to round up your result.



var averageTeamSales = function (salesTeam) {
//input: array of objects(salesTeam)
//output: avg of sales across all members
//make use of helper function for sum
//access needed information
//use sum to find average from whole list
var arr = [];
var sum = 0;
  salesTeam.forEach(function (member) {
    member = member.sales.slice(1);
    sum += parseInt(member);
    return sum;
  });

  return Math.ceil(sum / salesTeam.length);

};
averageTeamSales(salesTeam);

//***********************Part 4 ***********


function assert(expectedBehavior, descriptionOfCorrectBehavior) {
  if (!expectedBehavior) {
    console.log(descriptionOfCorrectBehavior);
  } else {
    console.log('test passed');
  }
}

//assert(averageTeamSales(salesTeam) === 7487, 'return average of sales');

//**************************Part 5********
