Thanks for the submission, but this, to me, feels like a Swagger (and its editor) tutorial.

Yes, Swagger uses JSON Schema, but there's nothing in this about using or writing JSON Schema or how it's related to describing APIs or generating docs.

It feels like it'd be a better fit for their blog (or an independent one).

Secondarily, is Swagger still a thing? Since Swagger (OpenAPI v2.0), there have been two releases of OpenAPI, 3.0 and 3.1, and they're planning on releasing v4 soon.

Hi @gregsdennis
Thanks for the review, actually there are 2 methods to write Swagger documentation for any endpoints through

1. YAML
2. JSON
   Since, with JSON we have many advantages over YAML, so created a one with the powerful capabilities of JSON, the blog is irrespective of any version of swagger we use today 😄

Looking forward to create better blog with the json-schema's 🤩
Feel free to close this PR 🙂
