"min" doesn't work

Ruby
1

When I execute this code:

[[2,"foo"],[1,"bar"]].min{|x|x.first}

I expected [1,"bar"] as a result, but I get the other entry. Why?

I found a solution, problem was that it expects a code block with 2 parameters. So this works: min{|x,y|x.first<=>y.first}. But is there a simpler or better way?

There’s min_by:

[[2,"foo"],[1,"bar"]].min_by &:first

Correct. You were making the mistake of using a max_by block with max, which takes a comparator instead. Either way, glad you figured it out.
