How to split a delimited string in Ruby and convert it to an array?

Question

I have a string

\"1,2,3,4\"

and I\'d like to convert it into an array:

[1,2,3,4]

How?

Answer 1

"12345".each_char.map(&:to_i)

each_char does basically the same as split(''): It splits a string into an array of its characters.

hmmm, I just realize now that in the original question the string contains commas, so my answer is not really helpful ;-(..
