  1. The Array object lets you store multiple values in a single variable. It stores a fixed-size sequential collection of elements of the same type. An array is used to store a collection of data, but it is often more useful to think of an array as a collection of variables of the same type.

  2. Index 0.

Ans 1:
An array is an object that makes allowance to store multiple values within the same single variable.

Ans 2:
The “shift” Array method is the one to use when wanting to remove the first element and return that first element as an output.

Ans: The property for indexing is zero based, therefore I think it is the first string/parameter within the parenthesis (). I think it is number one.

I just went on to the next video where Ivan explained the convention referencing number ‘0’ as the index for the first element in the variable. Got it!

  1. Arrays let us store more values into one variable. It is like a collection of multiple variables of the same type.

  2. For me, the syntax console.log(arrayName[0]); worked. As the counting starts at 0, we have to call the value number 0.

Q1. What do arrays allow us to do?
We can use arrays to store multiple values in a single variable.

eg.
var fruits = [“grapes”, “mango”, “banana”];
var year = [2000, 2001, 2002, 2004];

Q2. What index should you use in order to access the first element in an array?

Index 0 is used to access first element of the array.

fruits[0] gives grapes
year[0] gives 2000
