Title: Programming Ruby 3.2 (5th edition), p 23 (in Beta 6) –
After showing declaration of hashed “instrument_section” values, the sample outputs (following the sentence “Hashes are indexed using the same square bracket notation as arrays.” – two of the following three sample outputs have extraneous characters in the "# => " results:
p instrument_section[“oboe”] # => “woodwind”\n"string" should be: # => “woodwind”
p instrument_section[“cello”] # => “string”\nnil should be: # => “string”
p instrument_section[“bassoon”] # => nil (this one’s okay)
