This article introduces the relevant knowledge of "what are the matters needing attention in loading import export in ES6 module grammar". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

This time to bring you ES6 module syntax load import export,ES6 module syntax load import export what are the points for attention, the following is a practical example, let's take a look.

Export: to expose is to expose the interface

Import: introduce, literally, introduce an interface

Export {} export function demo () {} export var demo1

The two export above can be abbreviated as

Function demo () {} var demo1;export {demo, demo1} import {}

Accordingly, of course, there is import.

Import {demo,demo1} from.. path

Of course, you can also write another way to write import * as name from.. path and then quote it like name.demo ().

Export default

And there is export default.

You can only use export default once in a file.

Export default function demo () {}

And then when import

Import default

Import name (the name is chosen at random) from.. path

See this? no curly braces.

But

Precisely because the export default command actually outputs a variable called default, it cannot be followed by a variable declaration statement.

So export default var axi1 will report an error if you write it like this!

Var axi1

Export defatult a

This is also possible.

Export * from a module

This export* ignores the interface of the output of the module's export default

Well, if you say so, does a module of import * from fail to import the export default interface defined by the module?
