docs: the "publishing packages" page has no example 'exports' field with object syntax

[bjesuiter]

What I see

Every Example on the page https://jsr.io/docs/publishing-packages,
and especially in the section package-config-file
only has examples like

  "exports": "./mod.ts"

What I want

An example, which shows how to use "exports" with object syntax.
Especially I want to know:
How to write the main import in object syntax?
Do I write it like this?

"exports": {
  "/": "./mod.ts"
  "/extra": "./extra/mod.ts"
}

Or like this?

"exports": {
  ".": "./mod.ts"
  "extra": "./extra/mod.ts"
}

Or something completely different?

Exporting with multiple package entries:

{
  "name": "@example/my-package",
  "exports": {
    ".": "./mod.ts",              // default entry, "@example/my-package"
    "./foo": "./src/foo.ts",      // foo entry, "@example/my-package/foo"
    "./bar": "./src/other/bar.ts" // bar entry, "@example/my-package/bar"
  }
}

Shorthand syntax for just exporting only a default entry:

{
  "name": "@example/my-package",
  "exports": "./mod.ts"
}
