ruby convert array into function arguments

Question

Say I have an array. I wish to pass the array to a function. The function, however, expects two arguments. Is there a way to on the fly convert the array into 2 arguments? F

Answer 1

Use this

a.slice(*b)

It's called the splat operator

Answer 2

You can turn an Array into an argument list with the * (or "splat") operator:

a = [0, 1, 2, 3, 4] # => [0, 1, 2, 3, 4]
b = [2, 3] # => [2, 3]
a.slice(*b) # => [2, 3, 4]
