Splitting a string into an array ruby

Question

I am trying to turn this string

"a,bc,c"

into this array..

["a", "b", "c"]

I've used split on the comma & iterated through it but I'd like to find a cleaner way.

Thanks!

Answer 1

I will use #scan and #uniq method.

"a, bc,c".scan(/[a-z]/).uniq
# => ["a", "b", "c"]

Answer 2

Here we go, one option:

"a, bc,c".gsub(/\W+/, '').chars.uniq

 # Outputs:
 => ["a", "b", "c"]
