When using custom JavaScript objects, why should you use arrays of instantiate each object
individually?

A.
If the Web browser must parse the same code repeatedly, your computer will probably run
more slowly.

B.
Because JavaScript requires more time to instantiate objects individually than does Perl or
another scripting language.

C.
Arrays are more efficient because they are flexible and they are indexed, thus repetitive tasks
are easier to handle.

D.
Because JavaScript handles memory so poorly, it is impossible to write single variables that
function in any number.
