Implementing a custom string representation for a class you’re often printing out can save a LOT of time. The name of the method you need to implement is:
- Python: .__str__
- Ruby: .to_s
- JavaScript: .toString
- Java: .toString
- Go: String()
Also, pretty-printing libraries (like pprint in Python or awesome_print in Ruby) are great for printing out arrays/hashmaps.
