imports

The import statement is used to import bindings which are exported by another module. Ref. https://developer.mozilla.org/en-US/docs/web/javascript/reference/statements/import

Syntax

import defaultExport from "module-name";
import * as name from "module-name";
import { export } from "module-name";
import { export as alias } from "module-name";
import { export1 , export2 } from "module-name";
import { export1 , export2 as alias2 , [...] } from "module-name";
import defaultExport, { export [ , [...] ] } from "module-name";
import defaultExport, * as name from "module-name";
import "module-name";

defaultExport

Name that will refer to the default export from the module (one per module).

module-name

The module to import from. This is often a relative or absolute path name to the .js file containing the module, excluding the .js extension. Certain bundlers may permit or require the use of the extension;

name

Name of the module object that will be used as a kind of namespace when referring to the imports.

export, exportN

Name of the exports to be imported (specify individual named exports).

alias, aliasN

Names that will refer to the named imports.

The export parameters specify individual named exports, while the import * as name syntax imports all of them.
