The
.I =
operator tests for approximate equality. Dates compare
equal if they are on the same day (hour and minutes are ignored).
Strings compare equal if the left operand starts with the right operand.
The

operator tests for exact equality. The
.I !=
and
.I !==
operators are the negation of
.I =
and
.I ==
respectively.
