Solution 

before

import linearSearch from './linearSearch'

 

 

after

import { linearSearch } from './linearSearch.js' // 확장자 추가

export할 객체에 export 를 해줘야한다.

export function linearSearch(array, x) {
    const foundIndices = [];
    
    array.forEach((element, index) => {
        if (element == x) {
            foundIndices.push(index);
        }
    });

    return foundIndices;
}
