This time I bring you ES6 module syntax loading import export, ES6 module syntax loading import export What are the precautions, the following is a practical case, let's take a look.
export: exposure, that is, exposing the interface
import: introduction, just like the literal meaning, introduce the interface
export {}
export function demo(){}
export var demo1;The two above Export can be abbreviated as
function demo(){}
var demo1;
export {demo, demo1}
import {}Correspondingly, of course there is import
import {demo,demo1} from ..path
Of course, you can also write another way of writing import * as name from ..path Then when refers to , it is name.demo() like this
export default
And there is export default
A file can only be used once export default
export default function demo(){}
Then when importing
import default
import name(this The name is just chosen by me.) from ..path
I don’t see this without curly brackets
But
It’s precisely because the export default command actually only outputs a file called default variable, so it cannot be followed by a variable declaration statement.
So if export default var a=1 is written like this, an error will be reported! ! ! ! !
var a=1;
export defatult a ;
This is also possible
export * from a certain module
this export* will ignore the interface output by the export default of the module
If you say this, import * from a certain module will not be able to import the export default interface defined by the module
