Question:
I was reading in ruby's documentation on the link about ruby's default classes, but I saw that it has more classes than the documentation shows as yaml, where can I find these apis? I want to know which apis exist in ruby.
Answer:
this link is for the core methods. To consult Ruby's extra methods, the documentation itself already shows, but in another place. Follow the link .
PS: includes the YAML documentation you quoted!
Good luck.
