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,
}
*/
export const types = () => {}
is different from
export function types() { }
