- The official ruby documentation explains the observed difference between the outputs of `print` and `puts`. The important bits are as follows:
- <br>
- <h3>print</h3>
- For any non-string object given as argument (such as an array, for example), `print` invokes the object's `to_s` method and outputs the resulting string returned by `to_s`. Quote from doc ([link](https://docs.ruby-lang.org/en/master/ARGF.html#method-i-print)):
> Each given object that isn't a string will be converted by calling its to_s method.- And as it so happens, the `to_s` method of your array produces the `["Mad man", "Hey"]` output you observe (and which is also documented, [link](https://docs.ruby-lang.org/en/master/Array.html#method-i-to_s)).
- <br>
- <h3>puts</h3>
- On the other hand, `puts` behaves differently when provided with an array. Quote from doc ([link](https://docs.ruby-lang.org/en/master/IO.html#method-i-puts)):
> If called with an array argument, writes each element on a new line. Each given object that isn't a string or array will be converted by calling its to_s method.- Contrary to `print`, `puts` does NOT call the array's `to_s` method but rather directly outputs the array elements line-by-line.
- <br>
By the way, you can also achive almost the same output as `print` with `puts` by explictly invoking the `to_s` method like:- ```
- puts friends.to_s
- ```
- which will output
- > ["Mad man", "hey"]
- (It is only almost the same output as `print friends`, since `puts` writes a newline at the end of the output, whereas `print` does not -- unless of course you change the output record separator to a newline. See also hkotsubo's comment below.)
- The official ruby documentation explains the observed difference between the outputs of `print` and `puts`. The important bits are as follows:
- <br>
- <h3>print</h3>
- For any non-string object given as argument (such as an array, for example), `print` invokes the object's `to_s` method and outputs the resulting string returned by `to_s`. Quote from doc ([link](https://docs.ruby-lang.org/en/master/ARGF.html#method-i-print)):
- > Each given object **that isn't a string** will be converted by calling its to_s method.
- And as it so happens, the `to_s` method of your array produces the `["Mad man", "Hey"]` output you observe (and which is also documented, [link](https://docs.ruby-lang.org/en/master/Array.html#method-i-to_s)).
- <br>
- <h3>puts</h3>
- On the other hand, `puts` behaves differently when provided with an array. Quote from doc ([link](https://docs.ruby-lang.org/en/master/IO.html#method-i-puts)):
- > If called with an array argument, writes each element on a new line. Each given object **that isn't a string or array** will be converted by calling its to_s method.
- Contrary to `print`, `puts` does NOT call the array's `to_s` method but rather directly outputs the array elements line-by-line.
- <br>
- By the way, you can also achieve almost the same output as `print` with `puts` by explicitly invoking the `to_s` method like:
- ```
- puts friends.to_s
- ```
- which will output
- > ["Mad man", "hey"]
- (It is only almost the same output as `print friends`, since `puts` writes a newline at the end of the output, whereas `print` does not -- unless of course you change the output record separator to a newline. See also hkotsubo's comment below.)

The official ruby documentation will tell you as much. The important bits are as follows:- <br>
- For any non-string object given as argument (such as an array, for example), `print` invokes the object's `to_s` method and outputs the resulting string returned by `to_s`. Quote from doc ([link](https://docs.ruby-lang.org/en/master/ARGF.html#method-i-print)):
- > Each given object that isn't a string will be converted by calling its to_s method.
- And as it so happens, the `to_s` method of your array produces the `["Mad man", "Hey"]` output you observe.
- <br>
- On the other hand, `puts` behaves differently when provided with an array. Quote from doc ([link](https://docs.ruby-lang.org/en/master/Kernel.html#method-i-puts)):
- > If called with an array argument, writes each element on a new line. Each given object that isn't a string or array will be converted by calling its to_s method.
- Contrary to `print`, `puts` does NOT call the array's `to_s` method but rather directly outputs the array elements line-by-line.
- The official ruby documentation explains the observed difference between the outputs of `print` and `puts`. The important bits are as follows:
