Do you have to assign new names in JS arrays?

Hey y'all. . . I was just wondering if you had to assign new names for each array you write -- that is, if you have multiple arrays in one script.

For example:

var MyArray = new Array(2)
MyArrayObjects[0] = "whatever.";
MyArrayObjects[1] = "whatever again.";

Now if you wanted another array -- for the array, and for the objects in that array, do you have to assign new names for them? Like this:

var MyArray2 = new Array(2)
MyArrayObjects2[0] = "blah";
MyArrayObjects2[1] = "blah again";

Also, do you have to make the name of the objects in the array the same as the name of the array itself?

Thanks, I just wanted to know -- I'm bulding a JS "proglet" (little program).
