Question

I’d like to take a variable that I have, and turn it into an array separated by the character of my choosing. In the example below, that separator is %

dump = "1%2%3%apple%car%yellow"

into

Array= [1,2,3,apple,car,yellow]

Answer 1

Use String#split:

"1%2%3%apple%car%yellow".split('%')
# => ["1", "2", "3", "apple", "car", "yellow"]

(Note that every element of the returned array is a string, even the ones containing digits.)

From the docs:

split (pattern=$;, [limit]) → anArray

Divides
str into substrings based on a delimiter, returning an array of these
substrings.

You can pass a string like above ('%'), or a regular expression.
