Ruby - Array multiplication or JOIN operation

I have two arrays,

a = [1, 2]
b = [:a]

I want to get the result as 

[[1, :a], [2, :a]]

Is there any methods for this?

Also you can do it this way

[a,b*a.size].transpose
#=> [[1, :a], [2, :a]]

Use the Array#product:

a = [1, 2]
b = [:a]
a.product(b)
=> [[1, :a], [2, :a]]
