I'm writing a vanilla JS project and I'm encountering an issue.

test1.js:

export default foo;

function foo() {
    const something = "a";
}

test2.js:

import foo from test1.js;

foo();

console.log(something);

But when I try to run it in my browser (Firefox), I get Uncaught SyntaxError: export declarations may only appear at top level of a module.

Can anyone help? Thanks a lot!

Edit: Thanks a lot!

you can't call a variable which is inside function. Instead of that you can write :

export default foo;

function foo() {
    const something = "a";
    console.log(something)
}

then :

import foo from 'test1.js';

foo();

and in your HTML template : <script src="test2.js" type="module"></script>
