Checking string is empty
To check if a string is empty or not, we can use the built-in empty? method in Ruby.
The empty? method returns true if a string is empty; otherwise, it returns false.
Here is an example:
name = ""if name.empty? puts "string is empty"else puts "string is not empty"end
Output:
"string is empty"
Similarly, we can also use the length method to check for an empty string.
Example:
name = ""if !name.length puts "string is empty"else puts "string is not empty"end
If you want to check if a variable is nil or empty, you can check it like this in Ruby.
name = nilif name.nil? || name.empty? puts "string is empty"else puts "string is not empty"end
