PRACTICE THE FOLLOWING:

FUNCTION EXERCISES 
1) Take this array, carData and write a function
that returns the highest value of the property of year:

2) THEN write a function that returns all the models,
in Uppercase and sorts them. --alphabetically? 

3) THEN write a function that replaces all the 
properties of red and turns the value into cherry red.--2 objects that have property red. 

--------------------------------------------------------------------------------------------------
Take this array, carData and write a function
that returns the highest value of the property of year:

var carData=[
 {
    model:'Camry',
    color:'red',
    year:2013
  },
  {
    model:'Accord',
    color:'black',
    year:2016
  },
  {
    model:'Optima',
    color:'silver',
    year:2015
  },
  {
    model: 'focus',
    color: 'blue',
    year:2014
  },
 {
    model: 'i8',
    color: 'brown',
    year: 2017
  },
  {
    model: 'CTS',
    color: 'white',
    year: 2012
  },
  {
    model: 'pruies',
    color: 'red',
    year: 2011
  }
  ];
  

THEN write a function that returns all the models,
in Uppercase and sorts them. --alphabetically? 

**problem begins**
  Function inUppercase(array) {
  Return array.toUppercase.sort;
}

console.log((carData.model));

*Correct answer worked w/ Anna *
 var carData=[
 {
    model:'Camry',
    color:'red',
    year:2013
  },
  {
    model:'Accord',
    color:'black',
    year:2016
  },
  {
    model:'Optima',
    color:'silver',
    year:2015
  },
  {
    model: 'focus',
    color: 'blue',
    year:2014
  },
 {
    model: 'i8',
    color: 'brown',
    year: 2017
  },
  {
    model: 'CTS',
    color: 'white',
    year: 2012
  },
  {
    model: 'pruies',
    color: 'red',
    year: 2011
  }
  ];



function inUppercase(array) {
  return array.toUppercase.sort;
}

//console.log(inUppercase(carData.model));

function exampleFunction(data){
   var copy = [];
   data.forEach(function(elem){
     copy.push(elem.year);
   })
   return copy.sort();
  }
console.log(exampleFunction(carData));



THEN write a function that replaces all the 
properties of red and turns the value into cherry red.--2 objects that have property red. 

**problem begins**
Var redCars = [ 
Var  objectOne= {
 model:'Camry',
    color:'red',
    Year:2013
},
Var objectTwo = {
 model: 'pruies',
    color: 'red',
    year: 2011
}

Function changeColor(object) {
Delete redCars.color[“red”];
redCars.Color[]=”cherryred”;
}
------------------------------------------------------------------
*worked w/anna 7-18-17
var redCars = [
  {
    model: 'Camry',
    color: 'red',
    year: 2013
  },
  {
    model: 'Preis',
    color: 'red',
    year: 2011
  }
]

redCars.forEach(function(val, index) {
  // val and arr[index] point to the same object
  // so changing the object that val points to changes the object that   
  // arr[index] points to
 val.color = "cherry red";
})

alert(redCars[0].color);
alert(redCars[1].color);
console.log(arr);

Now if we wanted to write a function... how might we do this?
Let's have you practice and show me how you might
change the color to Cherry Red with a function.

*Chelsey work through w/ cleaner JS problem*
 
var redCars = [
  {
    model: 'Camry',
    color: 'red',
    year: 2013
  },
  {
    model: 'Preis',
    color: 'red',
    year: 2011
  }
]

function changeColor(object){ 
  object.color = 'cherry red';//object is changing property color to
  //'cherry red'
  return object;//returning object
}   

console.log(redCars);//printing array 

for(var i =0; i < redCars.length; i ++){//for loop is indexing through
  //array redCars
  redCars[i] = changeColor(redCars[i]);//redCars in the i position is 
  //equal to the function with the array(object name) in the 0 position.
}

console.log(redCars);//printing array with new color change
