The boolean 'False'
I was doing ruby challenge and I failed a question which asked what the value of false was!After the challenge i discovered false evaluates to truth soo... Why does the boolean 'false' evaluate to truth in ruby?

correct ans is : truthy.

@🌞 Brains
In Ruby only false & nil are falsey , everything else is truthy ..😊😊😊
the que u r referring in that
false is taken as string "false". so its truthy😎😎😎

if "false" is taken as string it's truthy
if false is taken as boolean it's false.

Well, there are two objects in Ruby that evaluates to false.
1) nil
2) false (as a boolean value)
I suppose that in challenge there is about "false" string, which evaluates to true.
This is tricky question, but still valid, and even cool imo :)

Apart from true and false, if you try to evaluate something that is not a boolean, ruby will treat them as truthy and falsey. Only false and nil are falsey, everything else is truthy. The boolean false is obviously false, but if it is a string “false”, then ruby treats it as truthy.

@Deoanshu Thakur Sorry if you don’t like me always challenging you 😅I don’t know why but I like to challenge someone who is better than me. If you think I am spamming and disturbing you, please let me know. I will stop challenging you then 😀

@sid you are wrong
"true" = truthy
"false" = truthy
- 1
"false" = truthy
"true" = falsey
