In Class: JavaScript Higher Order Functions and forEach

1. Use .map to take the code from the array below, and place the results in a new array where each value is 5 more than it was in the the original array. Print the new array.

let arr = [1, 2, 3, 4];
let plus5 = []; // new array to hold result

2. Use .map to create a new array of objects where each object has a property for index and value based on the elements in the array. Print the new array of objects.

let arr = [1, 2, 3, 4];
let num_objects = []; // new array to hold objects

Example Object to Return:

{
  index: 1,
  value: 2
}

3. Use .reduce to return the sum of all the numbers, each multiplied by 2. Print the final sum value.

let arr = [1, 2, 3, 4];
let nums_doubled_sum = []; // new variable assign the final sum

4. Use .filter to return a new array that contains only the even numbers. Print the new array.

let arr = [1, 22, 35, 40, 60, 2, 8, 100, 600, 3, 99, 71];
let even_vals = []; // new array to hold result

5. Use map to take an array of names and return a new array that contains instances of objects you instantiated from the class below

class Student{
        constructor(name){
                this.name = name;
        }
}

Iterate through the array returned using forEach and print the name property from each object instance in the array.
