How can I remove the last character of a string if it is a newline? "abc\n" --> "abc"

 

You can use the .chomp method in Ruby to remove the trailing newline character from a string. Here's an example:

ruby

string_with_newline = "abc\n"
string_without_newline = string_with_newline.chomp

puts "Original string: '#{string_with_newline}'"
puts "String after removing newline: '#{string_without_newline}'"

Output:

vbnet

Original string: 'abc'
String after removing newline: 'abc'

The .chomp method removes a newline character (\n) from the end of the string, if it exists. It's important to note that .chomp will only remove a single newline character from the end of the string. If there are multiple newline characters, only one will be removed.
