Its important to remember:
In C# an array is a data structure that contains several variables of the same type.
The number of dimensions and the length of each dimension are established when the array instance is created.
These values can’t be changed during the lifetime of the instance.
Arrays are zero indexed: an array with n elements is indexed from 0 to n-1
Objects with special numeric properties, accessed using square bracket syntax.
var myArray = [“first”, “second”];
myArray; // “first”
