In Ruby, we assign values to variables using =
, the assignment operator. But if we’ve already used =
for assignment, how do we check to see if two things are equal? Well, we use ==
, which is a comparator (also called a relational operator). ==
means “is equal to.” When you type
x = 2 y = 2 if x == y print "x and y are equal!" end
you’re saying: “if x equals y, print ‘x and y are equal!’” You can also check to see if two values are not equal using the !=
comparator.
Instructions
1.
We’ve got two variables in the editor: is_true
and is_false
. Replace the __
with ==
or !=
to make is_true
evaluate to true
and is_false
evaluate to false
.
