Given the following code var myArray 123456 function someFu

Given the following code:

var myArray = [1,2,3,4,5,6];
  
function someFunc(array) {
var s = 0;
for(var i = 0; i < array.length; i++) {
s = s + array[i];
}
return (s / array.length);
}
  
var a = someFunc(myArray);

What will variable a\'s value be after the code finished? What is the purpose of the function someFunc?

A. Value: 4

The factorial value of all myArray\'s numbers

B. Value: 3.5

The average value of all numbers in myArray

C. Value: NaN

It doesn\'t do anything

D. Value: 21

Is the sum of all values

E. Value: 3.5

Some random number

Solution

var myArray = [1,2,3,4,5,6];   //Declares an array.
  
function someFunc(array) {   //Function takes array as input.
var s = 0;               //Initializes s to 0.
for(var i = 0; i < array.length; i++) {   //Loop runs for values of i from 0 to 5.
s = s + array[i];   //Every value is added to the array.
}
return (s / array.length);   //The average of the array elements is returned.
}
  
var a = someFunc(myArray); //The average of the array myArray is stored in a.

So, the average is: (1 + 2 + 3 + 4 + 5 + 6) / 6 = 3.5

So, the answer is:

B. Value: 3.5

The average value of all numbers in myArray
