How to build a Ruby hash out of two equally-sized arrays?

Question

I have two arrays

a = [:foo, :bar, :baz, :bof] 

and

b = ["hello", "world", 1, 2] 

I want

{:foo => "hello", :bar => "world", :baz => 1, :bof => 2} 

Any way to do this?

Answer 1

h = Hash[a.zip b] # => {:baz=>1, :bof=>2, :bar=>"world", :foo=>"hello"} 

...damn, I love Ruby.

Answer 2

Just wanted to point out that there's a slightly cleaner way of doing this:

h = a.zip(b).to_h # => {:foo=>"hello", :bar=>"world", :baz=>1, :bof=>2} 

Have to agree on the "I love Ruby" part though!
