You can use curly braces to import implicitly and selectively from another module functions or objects and so on.
// import implicitly one function and one constant from example.js
import { a, b } from 'example'
example.js
// export a and b but kept c private to example.js
export const a => { ... }
export const b = "hello"
const c = "private, not visible to the outside"
