Construct hash by using two arrays Ruby

Question

I have two array's as follows:

["first_name", "last_name", "email_id",  "company"]
["Andy", "Martin", "[email protected]",  nil]

I need to construct this as hash as like this.

{"first_name"=>"Andy", "last_name"=>"Martin", "email_id"=>"[email protected]", "company"=>nil}

Is it possible in Ruby? If, then how to do that?

It works well in irb, but not in my project. It gets constructed in this way.. {["first_name", "last_name", "email_id", "company"]=>["Andy", "Martin", "[email protected]", nil]} — Dinesh

Do this using Array#zip:

h1 = ["first_name", "last_name", "email_id",  "company"]
h2 = ["Andy", "Martin", "[email protected]",  nil]

p Hash[h1.zip(h2)]

# >> {"first_name"=>"Andy", "last_name"=>"Martin", "email_id"=>"[email protected]",    "company"=>nil}

Thanks for that. I didn't know about the zip method, I was just about to suggest using a for loop, but this way is much better

But this constructs this way: {["first_name", "last_name", "email_id", "company"]=>["Andy", "Martin", "[email protected]", nil]}

Even this works for me

h1 = ["first_name", "last_name", "email_id",  "company"]
h2 = ["Andy", "Martin", "[email protected]",  nil]

Hash[[h1,h2].transpose]

# >> {"first_name"=>"Andy", "last_name"=>"Martin", "email_id"=>"[email protected]",    "company"=>nil}
