Question

I have two variables a and b. I want to compare both a and b to a value, say 10.

I can do it like this:

10 == a && 10 == b

But, I was wondering if there is any way to write it in a single expression? (E.g. like a == b == 10)

Answer 1

[a,b,3].all? {|x| x==10}

but in this case

[].all? {|x| x==10}

will also return true
