If I have an array of strings in ruby and I want to get the resulting array, what is the best way of doing it?

array = ["string_apple", "string_banana", "string_orange"]

desired_result = [["string", "apple"], ["string", "banana"], ["string", "orange"]]

My current attempt:

array.map(|r| r.split("_"))

ruby arrays split regex string

You need map{...}, not map(...) for correct syntax in Ruby here:

array = ["string_apple", "string_banana", "string_orange"]

# Assign to a different array:
split_array = array.map{ |s| s.split(/_/) }

# Or modify the original array in place:
array.map!{ |s| s.split(/_/) }

# [["string", "apple"], ["string", "banana"], ["string", "orange"]]
