This article mainly introduces the relevant knowledge of ES6 module grammar loading method, the content is detailed and easy to understand, the operation is simple and fast, and it has a certain reference value. I believe you will gain something after reading this ES6 module grammar loading method article. Let's take a look at it.

Export: to expose is to expose the interface

Import: introduce, literally, introduce an interface

Export {}

Exportfunctiondemo () {}

Exportvardemo1

The two export above can be abbreviated as

Functiondemo () {}

Vardemo1

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*asnamefrom..path and then quote it like name.demo ().

Exportdefault

And there is exportdefault.

You can only use exportdefault once in a file.

Exportdefaultfunctiondemo () {}

And then when import

Importdefault

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

See this? no curly braces.

But

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

So exportdefaultvara=1 will report an error if he writes like this!

Vara=1

Exportdefatulta

This is also possible.

A module of export*from

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

In that case, does a certain module of import*from fail to import the exportdefault interface defined by the module?
