Default Export
export default / default imports.
`export default function greet(...) {...}` in greet.ts binds its export under the synthetic key "default" — importable here as `import greet from './greet'` (any local name works; unlike a named import, there's no `{ ... }` list and no fixed name to match). A default import can also be combined with a named-import list in one statement, as below.
import greet, { shout } from './greet'
console.log(greet("world")) // hello world
console.log(shout("hi")) // HIView source on GitHubexamples/imports/default_export.ts
