What does `app.use(bodyParser.json())` do?

For: bodyParser.urlencoded({extended: ...}) my research shows me that if extended: true , then you can parse nested objects, or generally any type. However, if you set extended: false , then you can only parse strings or arrays. But what does ... app.use(bodyParser.json()) mean exactly? I mean, yes... I know the docs mention that it parses json. But I am still confused. I have noticed applications that set extended: true do NOT use bodyParser.json() at all. But applications that extended: false tend to use bodyParser.json() . Why is this? At the end of the day, both applications are able to
