Know all Angular versions


Angular stands out as a flexible framework in the changing web development realm. Introduced initially as AngularJS in 2010 by Google, Angular has changed to become the efficient and feature-rich framework we know today. This article explores the angular version history, features, and distinctions between versions of Angular, providing a guide to comprehending its growth and capabilities.


Table of Contents:


What Is Angular?

Angular serves as both a platform and framework for constructing intricate web applications. Utilizing TypeScript, a typed extension of JavaScript, simplifies the process of building durable, maintainable, and testable applications. Its component-based structure promotes reusability and modularity, empowering developers to create user experiences.

What is a Single-Page Application?

A Single Page Application (SPA) is a web application that loads a single HTML page and updates content dynamically as users engage with the application. SPAs enhance the user experience by reducing page reloads and lessening server load through their fluidity and responsiveness. Angular excels in crafting SPAs by equipping developers with tools for managing routing, state control, and data flow.

What is a Cross-Platform Application?

A cross-platform application is created to operate on operating systems and devices without modifications. It facilitates cross-platform development, enabling developers to construct web, mobile, and desktop applications using a codebase. This feature reduces development time and effort, significantly guaranteeing platform user experiences.
