In Ruby, the <=> operator, also known as the
spaceship operator, facilitates case-inclusive
string comparisons.
If string1 and string2 are the two
strings you want to compare, the result
will be an integer that indicates the
relationship between the two strings.
- If the result is 0, it indicates that both strings are equal.
- If the result is a positive number, it signifies that
string1 comes after string2 in a case-sensitive dictionary order.
- If the result is a negative number, it means
string1 precedes string2 in a case-sensitive dictionary order.
- If the result is
nil it means that the two are incomparable.
While casecmp specifically targets string
comparison and is case-insensitive, the <=>
operator is a more versatile method capable of
handling different data types and considers case in
its comparison.
