Why do we tag ".json" to the end when we require body-parser?
const jsonParser = require('body-parser').json
What does the .json do? Usually I just require modules without adding anything after the parentheses.

body-parser middleware package has different parsing options for handling and transforming data. These include JSON, text, url-encoded form data, and raw data. Requiring the package as
require('body-parser).json; simply provides a shorter way for calling it later for use instead of using it like this ->
bodyParser.json() you can use it like so ->
// requiring the package const bodyParser = require('body-parser'); const jsonParser = require('body-parser').json; // using it for json (these do the same exact thing) app.use(bodyParser.json()); app.use(jsonParser());
It's more of a styling preference than anything. Hope this helps. -- Drew
