### Latest Advancements <a href="#hud1f2sd99j" id="hud1f2sd99j"></a>

This module introduces cutting-edge technologies that are transforming how web and mobile applications are built, deployed, and experienced by users. These technologies focus on improving performance, user experience, development efficiency, and scalability.

#### Progressive Web Apps (PWAs) <a href="#id-2odrczgr2u32" id="id-2odrczgr2u32"></a>

* PWAs combine the best features of web and mobile apps, providing a native app-like experience.They work in the browser but feel like mobile apps - fast, installable, offline-ready, and engaging.
* **Key Features:**
  * **Offline Capabilities**: PWAs use Service Workers to cache content and allow the app to work offline or in low-connectivity environments.
    * Service Workers intercept network requests and serve cached content, ensuring that users can interact with the app even when they lose internet access.
  * **App-like Experience**: PWAs mimic the feel of native mobile apps by loading quickly and providing smooth, interactive user interfaces.
    * PWAs can be added to the home screen of a device, making them easily accessible like any native mobile app.
  * **Push Notifications**: Keep users engaged with updates and messages even when the app is closed.
  * **Responsive Design:** Seamlessly adapts across devices- mobile, tablet, desktop.
  * **Web App Manifest:** A JSON file(manifest.json) that defines how the app appears to the user (icon, name, theme).
    * Enables “Add to Home Screen” prompts.
* **Benefits:**
  * **Faster load times:** PWAs are optimized for fast loading, even in areas with slow internet connections, thanks to caching and preloading mechanisms.
  * Works on any device (mobile, tablet, desktop)
  * **No app store:** No need for users to install via app stores
  * **Reduced Development Overhead:** Allow developers to maintain a single codebase for both web and mobile, reducing duplication of effort compared to maintaining separate native apps.
* **Example: Twitter Lite**- A lightweight version of Twitter that works well on slow connections and can be added to the home screen.

#### WebAssembly (Wasm) <a href="#id-677i43pcbwe9" id="id-677i43pcbwe9"></a>

* WebAssembly (Wasm) is a low-level, binary instruction format that allows code written in languages like C, C++, Rust to run in the browser with near-native performance.
* Wasm is designed to work alongside JavaScript to enable use cases where JavaScript falls short in performance.JavaScript is great for general-purpose scripting and UI work, but it's not ideal for CPU-intensive tasks like:
  * Complex mathematical computations
  * Real-time video, audio, or image editing.
  * Machine learning and data visualization.
  * High-performance simulations (physics, finance, CAD).
  * Game development in the browser (e.g., 3D engines like Unity).
  * Running legacy or cross-platform apps in the browser (e.g., AutoCAD, Figma).
* **Key Features:**
  * **High Performance:** Compiled to binary → Runs much faster than JavaScript for compute-heavy tasks.
  * **Browser Compatibility:** Supported by all modern browsers (Chrome, Firefox, Safari, Edge).
  * **Language Interoperability:** Enables C/C++/Rust code to be used in web apps.
  * **Low-Level Access**: Can access hardware-level features for intensive tasks.
* **Integration with JavaScript:**
  * Write performance-heavy parts in C/C++/Rust.
  * Compile it to .wasm, a binary format
  * Import .wasm module in JavaScript using the WebAssembly API.
  * Call its functions just like JS functions.
  * The browser runs that binary code using its Wasm engine, which is built into the JavaScript engine (like V8 in Chrome).

#### Micro Frontends <a href="#bczybgozok3e" id="bczybgozok3e"></a>

* Micro Frontends apply the Microservices philosophy to frontend development — splitting a large monolithic frontend into smaller, manageable, independently deployable units.
* **Key Features:**
  * **Modular Development**: Each team can own and build a feature or section of the UI independently.
  * **Independent Deployment**: Teams can deploy their parts of the frontend without affecting other parts.
  * **Decoupling**: Different frontend technologies can be used for different parts of the application.
