can I export more than one function per file ? it seems like when I do that , the second function ovverides the first one ,
example :
in my index.js file :
export default function aFnt(){
console.log("function a");
}
export default function bFnt(){
console.log("function b");
}
then when I import it in my file :
import aFnt from "./index";
console.log("aFnt : ",aFnt);
the result of the console.log is bFnt
what exactly is the case here ? do I have to create a new file per function ? that is not very practical , any solution or workaround ?

Export Default is used to export only one value from a file which can be a class, function, or object. The default export can be imported with any name.
What is export default used for? Export defaults are used to export a single module, variable, expression, or function from a JavaScript file so that it can be used in any other file of either the same program or even in an entirely different program.
return "This a default export." export { fun as default , x, y, square }; While importing this module. js we can use any name for fun because it is a default export and curly braces for other named exports.
Every module can have two different types of export, named export and default export. You can have multiple named exports per module but only one default export.
ES6 | Import and Export. The ES6 is a JavaScript standard. With the help of ES6, we can create modules in JavaScript. In a module, there can be classes, functions, variables, and objects as well. To make all these available in another file, we can use export and import.

Default Export: (export default) Concerning the default export, there is only a single default export per module. A default export can be a function, a class, an object or anything else. This value is to be considered as the “main” exported value since it will be the simplest to import.

madox2's answer totally works if you want to import named functions.
If you still want to import the default, there's another technique:
function a() {}
function b() {}
export default { a, b }
and when you import:
import myObject from './index.js';
myObject.a(); // function a
myObject.b(); // function b
I hope this helps!

You can use named export instead of default:
export function aFnt(){
console.log("function a");
}
export function bFnt(){
console.log("function b");
}
and import it like:
import {aFnt, bFnt} from "./index";
