Print nothing using p() - Ruby

Question

I'm stumbling on using a ternary with the p() function in ruby. My code is:

 p i.prime?? i:''

Problem is, when i is not prime, it displays quotes instead of displaying nothing.

How do I fix this and make it print nothing? I don't want to print whitespace either. just nothing.

Since you mentioned code golf: note that the `if` variant is shorter here. — Stefan, Aug 03 '20 at 08:12

Check the difference between p and puts here: p vs puts in Ruby

For your question, sticking with the ternary, try just:

i.prime? ? (p i) : ''

Works perfectly. I'm trying a code golf problem, so I don't want to use puts. – Razetime Aug 03 '20 at 06:05
