What is the simplest way to get a substring in Ruby by removing a specific number of characters from the end?
I have the following string:
a_string = "a1wer4zx"
I want to remove the last 3 characters, resulting in "a1wer"
. Currently, my approach feels overly complicated:
an_array = a_string.split(//, (a_string.length - 2))
an_array.pop
new_string = an_array.join
What is a more efficient way to achieve this using Ruby substring operations?
