its for parallel routes

its page.js on first navigation inside of a parallel route

any example?

only the docs

parallel routes current implementation is pretty half cocked

i cant think of a single valid usecase of it.

@DirtyCajunRice | AppDir @Chestnut-backed Chickadee the documentation lacks information about default.js

at the time this question was posted, the documentation of default.js was still wip. now it's complete already, you can go there and learn how default.js works
