What is the purpose of import assertions in ES modules?
// math.js
export const add = (a, b) => a + b;
// test.js
import { add } from './math.js' assert { type: 'module' };
// Using import assertions
import data from './data.json' assert { type: 'json' };
Import assertions serve multiple purposes in ES modules: 1) They allow specifying the expected type of the imported module, 2) They enhance security by ensuring modules are of the expected type, 3) They enable importing non-JavaScript resources with type checking, 4) They help prevent accidental execution of malicious code, 5) They're particularly useful for importing JSON and other data formats safely, 6) They provide a standardized way to handle different module types, 7) They're part of the broader module security features in JavaScript.
