Pros and Cons of Angular

Angular’s biggest strength is its component-based architecture. Applications are broken down into smaller, reusable components that enhance code quality—leading to cleaner, more organized, and less error-prone development.

However, Angular’s rigor can also be a drawback: its steep learning curve often deters developers. Defining a single component may require multiple files, dependency injections, and lifecycle interfaces, making development feel complex and time-consuming for smaller projects.

What is Angular Useful For?

Angular shines in building scalable, enterprise-grade applications across platforms and devices. Features like modularization, dependency injection, RESTful API handling, and AJAX support make it ideal for large-scale projects.

Major brands such as Rockstar Games, YouTube TV, NBA.com, Google Cloud, Crunchbase, and Udacity use Angular to streamline their development workflows.

How to Migrate to Angular?

Migrating from AngularJS to modern Angular (TypeScript-based) often involves significant code refactoring. The process depends on your project's architecture and complexity. Fortunately, AngularJS and Angular can coexist within the same application, easing the transition.

Migration typically begins by assessing your current AngularJS version, then utilizing TestBed—Angular’s testing utility—for incremental upgrades. However, TestBed can become slow when managing thousands of tests simultaneously.

Angular vs JavaScript

JavaScript is a scripting language used to build dynamic websites, while AngularJS (the original version) is a now-deprecated framework built on JavaScript. AngularJS followed an MVC (Model-View-Controller) design, helping to create dynamic single-page applications (SPAs).

JavaScript broadly handles DOM manipulation, interactivity, and UI enhancements, while Angular (and AngularJS) offered structure and scalability for complex application development.

AngularJS vs Angular (TypeScript)

AngularJS (based on JavaScript) has been replaced by Angular (based on TypeScript). Angular introduces a modernized architecture, a powerful CLI, modular development, and a shift from MVC to a more component-driven approach. It’s faster, more secure, and fully compatible with today’s major browsers and devices.
