Creating components is a core concept in Angular because components are the building blocks of any Angular application. 🔹 What is an Angular Component? A component in Angular controls a view (HTML template) and contains logic to support that view (written in a TypeScript class). It typically consists of: A .ts file (logic) A .html file (template) A .css or .scss file (styling) 🔧 How to Create a Component ✅ Using Angular CLI (recommended) ng generate component component-name # OR ng g c component-name For example: ng g c user-profile This creates a folder like this: src/app/user-profile/ ├── user-profile.component.ts ← component logic ├── user-profile.component.html ← template ├── user-profile.component.css ← styles ├── user-profile.component.spec.ts ← test file 🧱 Anatomy of a Component user-profile.component.ts import { Component } from '@angular/core'; @Component({ selector: 'app-user-profile', temp...

Modules and Namespaces in TypeScript Modules and Namespaces in TypeScript Let’s break down Modules and Namespaces in TypeScript — both are mechanisms for organizing and reusing code, but they serve slightly different purposes and are used differently. 🔹 Modules in TypeScript ✅ What is a Module? A module is a file that contains code (classes, interfaces, functions, variables, etc.) and exports them so they can be reused in other files by importing . 🔧 How to Create and Use a Module math.ts (a module) export function add(a: number, b: number): number { return a + b; } export const PI = 3.14; main.ts (importing the module) import { add, PI } from './math'; console.log(add(5, 10)); // 15 console.log(PI); // 3.14 Modules follow ES6 module syntax and are commonly used in Angular and modern TypeScript projects. 🔹 Namespaces in TypeScript ✅ What is a Namespace? ...

Functions and Arrow Functions in TypeScript Functions and Arrow Functions in TypeScript Great! Let’s dive into Functions and Arrow Functions in TypeScript (used throughout Angular apps for clean and modular code). 🔹 1. Traditional Functions A function is a reusable block of code that performs a specific task. ✅ Basic Syntax function add(a: number, b: number): number { return a + b; } console.log(add(5, 3)); // Output: 8 ➕ Optional & Default Parameters function greet(name: string = "Guest"): string { return `Hello, ${name}`; } console.log(greet()); // Hello, Guest console.log(greet("Alice")); // Hello, Alice 🔹 2. Arrow Functions Arrow functions offer a shorter syntax and lexical this binding, commonly used in Angular for callbacks and concise logic. ✅ Basic Syntax const multiply = (x: number, y: number): number => { return x * y; }; consol...

Classes and Objects in TypeScript Classes and Objects in TypeScript Awesome! Let's now cover Classes and Objects in TypeScript, which are at the core of building services, components, and models in Angular. 🔹 1. What is a Class? A class is a blueprint for creating objects. It encapsulates data (properties) and behavior (methods). ✅ Basic Syntax class Person { name: string; age: number; constructor(name: string, age: number) { this.name = name; this.age = age; } greet(): void { console.log(`Hello, my name is ${this.name}`); } } 🔹 2. Creating an Object You can create objects (instances) from a class using the new keyword. const person1 = new Person("Alice", 30); person1.greet(); // Output: Hello, my name is Alice 🔹 3. Access Modifiers Modifier Description ...

What is SQL Server? Microsoft SQL Server is a relational database management system (RDBMS) developed by Microsoft. It is designed to store, retrieve, manage, and analyze structured data efficiently. SQL Server uses Structured Query Language (SQL) to interact with databases and supports transaction processing, business intelligence (BI), and analytics applications . SQL Server operates on a client-server architecture , where clients (applications) send queries to the SQL Server, which processes the requests and returns the results. Why Use SQL Server? SQL Server is widely used due to its robust performance, security, scalability, and integration with Microsoft products. Here are the key reasons to use SQL Server: 1. Reliability & Performance Optimized Query Execution : SQL Server includes a query optimizer that improves execution speed for complex queries. In-Memory Processing : Features like In-Memory OLTP significantly improve transaction processing spee...

1️⃣ What is .NET? 🔹 .NET (Dotnet) is a free, open-source, cross-platform framework developed by Microsoft for building various types of applications, including: Web Applications Desktop Applications Cloud Services Mobile Apps Game Development IoT Applications 🔹 Key Characteristics of .NET ✅ Cross-platform – Runs on Windows, macOS, and Linux ✅ Language Interoperability – Supports multiple languages, including C#, F#, and VB.NET ✅ High Performance – Optimized runtime for fast execution ✅ Managed Code – Uses the Common Language Runtime (CLR) ✅ Automatic Memory Management – Uses Garbage Collection (GC) 2️⃣ Evolution of .NET .NET Framework (2002) – The original, Windows-only version .NET Core (2016) – A cross-platform, modular, open-source version .NET 5+ (2020-Present) – A unified platform (merging .NET Framework and .NET Core) 🔹 Current Version : .NET 8 (Latest as of 2024) 🔹 Major Components of .NET .NET Runtime – Execut...

What is Cloud Computing? 🌩️ What is Cloud Computing? Cloud Computing is the on-demand delivery of computing services —including servers, storage, databases, networking, software, analytics, and more— over the internet ("the cloud") . Instead of owning and maintaining physical data centers or servers, individuals and organizations can rent computing power and storage from cloud providers. 🚀 Key Characteristics Feature Description On-Demand Self-Service Users can provision resources as needed without human interaction. Broad Network Access Services are accessible over the internet from various devices. Resource Pooling Providers serve multiple customers using a multi-tenant model. Rapid Elasticity Resources can be scaled u...
