How do I remove blank elements from an array?

I have the following array

cities = ["Kathmandu", "Pokhara", "", "Dharan", "Butwal"]

I want to remove blank elements from the array and want the following result:

cities = ["Kathmandu", "Pokhara", "Dharan", "Butwal"]

Is there any method like compact that will do it without loops?

ruby array

Here is what works for me:

[1, "", 2, "hello", nil].reject(&:blank?)

output:

[1, 2, "hello"]

When I want to tidy up an array like this I use:

["Kathmandu", "Pokhara", "", "Dharan", "Butwal"] - ["", nil]

This will remove all blank or nil elements.
