How does React.lazy work?

Question

React

Hello, please tell me why if I write AddTodo like this:
const AddTodo = React.lazy(() => import('./Todo/AddTodo') )

everything works, but if:
const AddTodo = React.lazy(( ) => {
import('./Todo/AddTodo')
} )

then nothing works.

Answer 1

Because you need to return a value if you use curly braces:

const AddTodo = React.lazy(() => {
     return import('./Todo/AddTodo');
} )
