    We can use rescue in single line to return a value if code of that line raise an error/exception, example shown below-:

    Let say we have a hash:

    person  =  {:name => "ABC"}
    
    person[:name].downcase                               # "abc"
    

    code without rescue:

    person[:age].downcase                                  # NoMethodError: undefined method `downcase' for nil:NilClass
    

    code with inline rescue:

    person[:age].downcase rescue "Age not present"        # "Age not present"
