Core Concepts TypeScript leverages classes and interfaces to enforce type safety while supporting object-oriented design. Classes provide concrete implementations, whereas interfaces define structural contracts without implementation. class Employee { name: string; department: string; constructor(na...
Initialize the workspace structure and instal required dependencies. Create source directories and bootstrap the Node.js project. mkdir typeorm-db-demo && cd typeorm-db-demo mkdir src && npm init -y npm install reflect-metadata bcryptjs dotenv typeorm typeorm-naming-strategies ts-nod...
pnpm Overview & Installation pnpm is a fast, efficient package manager similar to npm and Yarn, with key advantages: Blazing-fast package installation Optimized disk space utilization Install via npm: npm install -g pnpm Common command equivalences between npm and pnpm: npm Command pnpm Equivale...
Intersection Types Intersection types combine multiple types into a single type using the & operator, declared with type. For example: interface Person { name: string; age: number; } interface Contact { name: string; phone: number; } type Combined = Person & Contact; const data: Combined = {...
TypeScript extends JavaScript by introducing optional static typing and class-based object-oriented features, designed for building scalable applications that compile to standard JavaScript for execution in browsers or other enviroments. Type Annotations Type annotations specify expected types for v...
1. Common Type Annotations Basic type annotation syntax example: let userAge: number = 24; Existing Types Inherited from JavaScript Primitive types: number, string, boolean, null, undefined, symbol Object types: object (includes arrays, plain objects, functions and other object values) New Types Int...
TypeScript extends JavaScript by introducing a static type system that validates data structures during compilation. This foundation relies on primitive definitions, explicit signatures, and automatic inference mechanisms. Core Primitive Definitions Numeric values encompass both integers and floatin...
To augmant PixiJS coordinate handling, extend the IPoint interface and attach mathematical utilities directly to the Point and ObservablePoint prototypes. Create a dedicated extension module and register the new signatures within the PixiJS namespace. import { IPoint, Point, ObservablePoint } from '...
TypeScript and JavaScript represent distinct language paradigms. TypeScript is a strongly typed language, whereas JavaScript is weakly typed. Strongly typed languages can support both static and dynamic typing models, while weakly typed languages primarily support dynamic typing. Strongly Typed vs....
Vue 3.0 introduced the Composition API, which, while powerful, initially felt more verbose for developers accustomed to the Options API. The Vue team addressed this feedback within the Single File Component (SFC) context by introducing the <script setup> syntax, a compile-time syntactic sugar...
