Learn
Now that you’re learning some of the more complex parts of the Ruby language, you can combine them to work some truly arcane magicks. For instance, remember when we told you that you could pass a Ruby method name around with a symbol? Well, you can also convert symbols to procs using that handy little &
.
Check it out:
strings = ["1", "2", "3"] nums = strings.map(&:to_i) # ==> [1, 2, 3]
By mapping &:to_i
over every element of strings
, we turned each string into an integer!
Instructions
1.
Using the example in the instructions as a guide, use collect
or map
to create the strings_array
from the numbers_array
. Each element of strings_array
should be the string version of the corresponding element from the numbers_array
(that is, it should go ["1", "2", "3"... "10"]
).
