What is the meaning of GET /posts.json comment?

In the PostsController every action has 2 comments:

# GET /posts
# GET /posts.json
def index
  ...
end

# GET /posts/1
# GET /posts/1.json
def show
  ...
end

# GET /posts/new
def new
  ...
end

# GET /posts/1/edit
def edit
  ...
end

# POST /posts
# POST /posts.json
def create
  ...
end

# PATCH/PUT /posts/1
# PATCH/PUT /posts/1.json
def update
  ...
end

# DELETE /posts/1
# DELETE /posts/1.json
def destroy
  ...
end

The first ones are pretty self-explanatory to me. However, I couldn't understand why the scaffold generates comments that include a .json version of HTTP requests?

Hi Ogulcan,

Scaffolding is mostly an educational tool to provide you with a somewhat dynamic example, and to demonstrate Rails best practices. If you have Jbuilder in your Gem files (included in Rails 4 by default), the scaffolding command will generate the files as a way to have a template for responding to a JSON query.

If you want to view the output, fire up your (local) server and visit: /posts.json
