Answer 1

The problem is that in most programming languages, any string that is not empty is considered 'true' .

if y == 'hello' || 'hi'

is the same thing as

if y == 'hello' || true.

Since the right operand is true, the whole expression will always be true. So if y == 'hello' || 'hi' doesn't really check anything.

Answer 2

Никита Шиляев Exactly!

Answer 3

if theres only a value in a condition, like in y == "a" || 1, it is always true, as 1 counts as true.
you can replace 1 with every value that is not 0 and it should always return true.
but if the value is 0, it is false as 0 represents false.

Answer 4

Anna, thank you for your answer! Thus, using OR condition with strings I should do y==“...” || y==“...” right?

Answer 5

Kevin, thank you a lot for your answer but the question is how to make an abridge form y==“hello”||”hi” work as y==“hello” || y==“hi”. Can you answer please?
