Hint. A Javascript array is a collection of values that can be saved into a single variable per Gabriel Cánepa.

Arrays in Javascript are instantiated with a set of enclosing brackets [...].

The brackets [...] house the collection of values, as follows:


var birds = ["parrot", "robin", "cardinal"];

;where bird of birds can be picked using the built in query-by-position algorithm, as follows:

Note. Just plug-in the index of the placeholder for the value you are attempting to expose right behind the name of the array.

Returns,


"robin"

;where the index zero(0) represents the value of first place in the array
