$ is a commonly defined (but not built-in) Javascript function that acts =
as
a shortcut to getElementById().=20

=3D=3D=3D is the standard JavaScript 'Identity' operator - the items =
being
compared must be equivalent and of the same type (no automatic type
conversion).

Where this would be true:

1 =3D=3D "1"

This would not:

1 =3D=3D=3D "1"

Hope that helps,
