How to split a string in Ruby and get all items except the first one?

Question

String is ex=\"test1, test2, test3, test4, test5\"

when I use

ex.split(\",\").first

it returns

\"test1\"
         


        

Answer 1

ex.split(',', 2).last

The 2 at the end says: split into 2 pieces, not more.

normally split will cut the value into as many pieces as it can, using a second value you can limit how many pieces you will get. Using ex.split(',', 2) will give you:

["test1", "test2, test3, test4, test5"]

as an array, instead of:

["test1", "test2", "test3", "test4", "test5"]
