In this article, we figure out the key differences between Angular and AngularJS open source tools for front end developers to make the usage of these frameworks, terms, and names more conscious. But before we start to compare, let’s clarify what these names mean.
Versions of Angular
Angular (a.k.a. Angular 1) is a popular framework to build small and big web apps. While Angular is written in TypeScript (which is a superset of JavaScript), AngularJS is based on JavaScript itself. Actually, AngularJS is the first major version of Angular released by Google in 2012.
The second major version of Angular was completely rewritten and lost “JS” in its name since it’s not based on JavaScript anymore and doesn’t have an upgrade patch from AngularJS. These are completely different (on implementation level) frameworks. When we talk about Angular, we mean Angular 2, Angular 4-8 and the latest version of Angular – Angular 9, which was released in 2020.
Here’s a list of Angular 9 features:
- Smaller bundle sizes and augmented performance
- Faster testing
- Better debugging
- Improved CSS class and style binding
- Improved type checking
- Improved build errors
- Improved build times, enabling AOT on by default
- Improved Internationalization
- The Ivy compiler: The default use of the Ivy compiler is the most important feature of Angular 9, Ivy is what actually designed to solve the major problems of Angular i.e the performance and large file size
- Selector-less bindings support for Angular Ivy
- Support for TypeScript Diagnostics Format
- Support for more scopes in providedIn
- A New Type-Safe TestBed.inject() Method Instead of TestBed.get()
- Improvements to differential loading
- AOT compilation everywhere
- Bundle sizes
- Globalization
- Additional provider scopes
- Improved developer experience
- New debugging API in development mode
- Strict mode
- Improved component and directive class inheritance
- Latest TypeScript versions
- Improved server-side rendering with Angular Universal
- Improved styling experience
- Stable Bazel release as an opt-in option
