Eloquent Ruby, Second Edition: safe navigation explanation (page 44)

It would be excellent to have a little more explanation about why the code returns false for the last example in the section: docs&.​first​&.​words​&.​first​&.​reverse.​

Good catch!

I accidentally pulled in the wrong code example here. The correct bit of code is:

(1 == 0)&.to_s

Since 1 == 0 is false and false is not nil, we get “false”.

Thanks!
