1. What do arrays allow us to do?
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.
Arrays allow us to hold more than one value in a variable.

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

Array index starts from zero. So first element is in index zero.

  1. What do arrays allow us to do?
    Arrays are used to store data into a collection of variables of the same type and can be accessed through the use of zero-based index.
  2. What index should you use in order to access the first element in an array?
    myArray[0] shows the first element because computers count from zero rather than one like humans do.
