Why is my export const function not importing properly?

Question

So I'm creating a simple react app that export a file that contains a function that returns an array of objects:

export const listStudents = () => {
    return [{name:"Ljuben", lastName:"Angelkoski", indeks:"161161", nasoka:"KNI"},
            {name:"Pere", lastName:"Anastasov", indeks:"17350", nasoka:"PET"},
            {name:"Filip", lastName:"Shabanoski", indeks:"173521", nasoka:"PET"},
            {name:"Martin", lastName:"Krsteski", indeks:"163544", nasoka:"KNI"},
            {name:"Nikola", lastName:"Nacevski", indeks:"154874", nasoka:"ASI"}]; // replace the empty array with actual array with at least 5 student objects
}

And in my main component I have this code:

import React, {Component} from 'react'
import listStudents from './repository/studentRepository.js'

class Main extends Component{
    constructor(props){
        super(props);

        this.state={
            students: listStudents
        }
    }

    render(){
        return (
            <h2></h2>
        )
    }
}

export default Main

However when I run the app it gives me this error :

./src/Main.js
Attempted import error: './repository/studentRepository.js' does not contain a default export (imported as 'listStudents').

Any ideas?

Edit: You need to properly `import` your `studentRepository.js` — Train, Nov 13 '18 at 16:32

Also change this.state={ students: listStudents } to this.state={ students: listStudents() } — Hemadri Dasari, Nov 13 '18 at 16:57

listStudents is a named export, so you must import it like this:

import { listStudents } from './repository/studentRepository.js'

If you don't want to change the import, you can use the default export for the function instead.

export default () => {
    return [/* ... */]; 
}

If you didn't mention default export in children.js ,so you need to import with name.

import { liststudents } from './children';

Or you have to mention default export in children like

export default const list = []

and also its a function in children.js .so to get data from it, you need to call it like.

 this.state = {
    students: listStudents()
 }

simpler way would be defined them as array like

export const listStudents = [...students arr]

Why is my export const function not importing properly?
