  In today’s hyper-connected world, users expect real-time interactions—whether it's chatting with support, receiving stock updates, or tracking delivery in motion. Traditional HTTP was never built for this level of immediacy. Enter WebSockets —the game-changer for real-time, two-way communication between clients and servers. What are WebSockets? WebSockets are a protocol that enables persistent, full-duplex communication between the client and the server over a single TCP connection. Unlike HTTP, which is request-response based, WebSockets allow data to flow freely both ways without repeatedly opening new connections. How WebSockets Work Handshake : It starts with an HTTP request to initiate the WebSocket connection. Upgrade : If the server accepts, the protocol switches from HTTP to WebSocket. Persistent Connection : Once established, both the client and server can send data at any time. WebSockets vs. HTTP Polling Use Cases of WebSockets...

Modern web applications are more powerful than ever—but with power comes complexity and performance bottlenecks. While JavaScript has been the dominant language of the web for decades, it has its limits, especially for performance-intensive tasks like video editing, 3D rendering, and gaming. Enter WebAssembly (WASM) — a game-changing technology that brings near-native performance to web applications. In this post, we’ll explore what WASM is, why it matters, and how it’s transforming front-end development. What is WebAssembly? WebAssembly is a low-level binary instruction format designed to run code at near-native speed in modern web browsers. It acts as a compilation target for languages like C, C++, Rust, and Go, allowing you to bring non-JavaScript code to the browser securely and efficiently. // Unlike JavaScript, you don’t write WebAssembly directly. // But here’s how you load a WASM module in JavaScript: fetch('example.wasm')   .then(response => respo...
