Features of JavaScript Modules
- Encapsulation: JavaScript modules offer encapsulation by defining private and public interfaces, allowing developers to control the visibility and accessibility of module members.
- Code Organization: Modules enable developers to organize code into logical units, improving maintainability and readability by reducing complexity and separating concerns.
- Dependency Management: Modules facilitate dependency management by specifying explicit dependencies between modules, making it easier to understand and reason about code dependencies.
- Browser Compatibility: JavaScript modules are supported by modern browsers and are compatible with tools like Webpack, Rollup, and Babel, making them suitable for building modular web applications.
Example of JavaScript Modules:
Step 1: Initialize the application using the following command.
npm init -y
Step 2: In Package.json, Put a line ( “type”: “module” ).
Folder Structure:
Code Example: Create the following files and add the following codes.
// mathUtils.js
export function cube(x) {
return x * x * x;
}
// main.js
import { cube } from './mathUtils.js';
const result = cube(10);
console.log(`The square of 10 is: ${result}`);

Differece between JavaScript Modules & NgModule
Modules play an important role in structuring and organizing the code of Javascript and Angular.js. They help us to use the code efficiently. Majorly NgModule in Angular.js and Modules in Javascript are widely used in different scenarios.
In this article, We will learn about Modules and their importance in Angular.js and Javascript.
