How important is HTML & CSS for React.js developers?

 HTML & CSS are very important for React.js developers — they’re like the foundation React builds on top of. Here’s why:

How important is HTML & CSS for React.js developers?

🧱 HTML (or JSX in React)

React uses JSX, which is basically JavaScript + HTML. If you don’t understand HTML structure, you’ll struggle to build components effectively.

  • Need to build buttons, forms, layouts? That's all HTML.

  • React components return JSX, and JSX is just HTML-like syntax.

  • Accessibility (ARIA, semantic tags) is crucial in modern apps — that’s HTML knowledge.

✅ You don’t need to memorize every tag, but you should be very comfortable with layouts, forms, and semantic HTML.

🎨 CSS

React doesn’t replace CSS. You still need to style everything.

  • You'll often write CSS Modules, styled-components, TailwindCSS, or inline styles — but the core is still CSS.

  • Understanding things like Flexbox, Grid, media queries, and positioning is essential.

  • CSS-in-JS makes styling more dynamic, but it still uses the same principles.

✅ You don’t have to be a designer, but you should know how to bring a design to life.

🔁 TL;DR: React ≠ Replacement for HTML & CSS

React is the logic layer and HTML/CSS are the presentation layers. Mastering all three makes you a complete front-end developer.

How does BGP prevent routing loops? Explain AS_PATH and loop prevention mechanisms.

 In Border Gateway Protocol (BGP), preventing routing loops is critical — especially because BGP is the inter-domain routing protocol used to connect Autonomous Systems (ASes) on the internet. 🔄 How BGP Prevents Routing Loops The main mechanism BGP uses is the AS_PATH attribute . 🔍 What is AS_PATH? AS_PATH is a BGP path attribute that lists the sequence of Autonomous Systems (AS numbers) a route has traversed. Each time a route is advertised across an AS boundary, the local AS number is prepended to the AS_PATH. Example: If AS 65001 → AS 65002 → AS 65003 is the route a prefix has taken, the AS_PATH will look like: makefile AS_PATH: 65003 65002 65001 It’s prepended in reverse order — so the last AS is first . 🚫 Loop Prevention Using AS_PATH ✅ Core Mechanism: BGP routers reject any route advertisement that contains their own AS number in the AS_PATH. 🔁 Why It Works: If a route makes its way back to an AS that’s already in the AS_PATH , that AS kno...

Explain the Angular compilation process: View Engine vs. Ivy.

 The Angular compilation process transforms your Angular templates and components into efficient JavaScript code that the browser can execute. Over time, Angular has evolved from the View Engine compiler to a newer, more efficient system called Ivy . Here's a breakdown of the differences between View Engine and Ivy , and how each affects the compilation process: 🔧 1. What Is Angular Compilation? Angular templates ( HTML inside components) are not regular HTML—they include Angular-specific syntax like *ngIf , {{ }} interpolation, and custom directives. The compiler translates these templates into JavaScript instructions that render and update the DOM. Angular uses Ahead-of-Time (AOT) or Just-in-Time (JIT) compilation modes: JIT : Compiles in the browser at runtime (used in development). AOT : Compiles at build time into efficient JS (used in production). 🧱 2. View Engine (Legacy Compiler) ➤ Used in Angular versions < 9 🔍 How It Works: Compiles templat...

What are the different types of directives in Angular? Give real-world examples.

In Angular, directives are classes that allow you to manipulate the DOM or component behavior . There are three main types of directives: 🧱 1. Component Directives Technically, components are directives with a template. They control a section of the screen (UI) and encapsulate logi c. ✅ Example: @Component ({ selector : 'app-user-card' , template : `<h2>{{ name }}</h2>` }) export class UserCardComponent { name = 'Alice' ; } 📌 Real-World Use: A ProductCardComponent showing product details on an e-commerce site. A ChatMessageComponent displaying individual messages in a chat app. ⚙️ 2. Structural Directives These change the DOM layout by adding or removing elements. ✅ Built-in Examples: *ngIf : Conditionally includes a template. *ngFor : Iterates over a list and renders template for each item. *ngSwitch : Switches views based on a condition. 📌 Real-World Use: < div * ngIf = "user.isLoggedIn...
