Till now
we defined array using [], but JavaScript also provides a constructor function
Array(), to define an array. It is available in two forms, one takes 1 argument
and other takes 2 arguments.
Array(10)
: Create an array of size 10 elements.
Array(10,
12) : Create an array with elements 10 and 12, [10, 12].
