• ​AirBNB JavaScript Style Guide: Modules​

  • 10.1 Always use modules (import/export) over a non-standard module system.

  • 10.2 Do not use wildcard imports.

  • 10.6 In modules with a single export, prefer default export over named export.

    • Interpretation: multiple exports allowed

• Confusing as hell

  • ESM vs CommonJS vs ES6

If using export default use import var from module:

export const foo = 42
export default 21;

If you want the 21, use import bar from './input';

import barImport from './input';
console.log(barImport); // 21
​
const barRequire = require('./input');
console.log(barRequire);
/*
{
    foo: 42,
    default: 21,
}
*/

Notes

export const types = () => {}

is different from

export function types() { }
