exportimport module
export
create a new filemj.js
export function plus(a, b) {
return a + b
}
import
Import needs to be placed in the script tag of type module
import * as m from './mj.js';
alert(m.plus(1, 2));
Use import() to import the module, the script where import() is located does not need to set the type to module. The
import() function returns a Promise object
import('./mj.js').then(r => {
alert(r.plus('hello', 'world'))
})
