Angular 12 is the latest major release of the Angular framework as of my knowledge cutoff date (September 2021). It was released by Google in May 2021 and includes several new features and improvements over the previous version, Angular 11. Some of the key features and improvements introduced in Angular 12 include:
- Faster builds : Angular 12 includes improvements to the build process, including better incremental compilation and caching, which can help to speed up build times for large applications.
- Simplified styling : The new style: "block" option makes it easier to style individual components by encapsulating CSS styles within the component's scope, rather than relying on global styles.
- Improved testing : Angular 12 includes several improvements to testing, including faster test execution times and improved debugging capabilities.
- Better performance : Several performance improvements have been introduced in Angular 12, including faster change detection and more efficient rendering of animations.
- New APIs and features : Angular 12 introduces several new APIs and features, including a new takeUntil operator for RxJS, improved support for TypeScript 4.2, and better support for accessibility.
Overall, Angular 12 is a significant update to the Angular framework, offering several new features and improvements that can help to improve the development process and enhance the performance of Angular applications.
Use of Angular
Angular is a powerful front-end web application development framework that can be used to create a wide range of web applications, from simple websites to large-scale enterprise applications. Some of the key uses of Angular include:
- Building dynamic web applications : Angular is particularly well-suited for building dynamic web applications that require a lot of interactivity and data manipulation. Its two-way data binding feature allows developers to create responsive user interfaces that automatically update in real-time as data changes.
- Building dynamic web applications : Angular is particularly well-suited for building dynamic web applications that require a lot of interactivity and data manipulation. Its two-way data binding feature allows developers to create responsive user interfaces that automatically update in real-time as data changes.
- Simplifying development : Angular's component-based architecture makes it easier to break down complex applications into smaller, more manageable pieces. This can help to simplify development and make it easier to maintain code over time.
- Improving performance : Angular includes a number of built-in optimizations that can help to improve the performance of web applications, including lazy loading, ahead-of-time (AOT) compilation, and tree shaking.
- Building scalable applications : Angular is designed to be scalable, allowing developers to build applications that can handle large amounts of traffic and data without slowing down or crashing.
- Creating cross-platform applications : Angular can be used to create web applications that run on a wide range of devices and platforms, including desktops, laptops, tablets, and smartphones.
- Developing progressive web applications (PWAs) : Angular provides support for building PWAs, which are web applications that provide a native app-like experience to users, including features like offline support, push notifications, and access to device hardware.
Overall, Angular is a powerful and versatile framework that can be used to build a wide range of web applications, from small websites to large-scale enterprise applications. Its popularity is due to its scalability, robustness, and flexibility, making it a preferred choice for modern web application development.
Difference between AngularJS and Angular
AngularJS and Angular are two different frameworks for building web applications, with some key differences in their architecture, features, and performance.
AngularJS (often referred to as "Angular 1") is an older version of the Angular framework, released in 2010. It is based on JavaScript and offers a number of powerful features for building dynamic web applications, including two-way data binding, dependency injection, and reusable components. However, AngularJS has some limitations, including slower performance and a more complex architecture that can be difficult to scale and maintain over time.
Angular, on the other hand, is a newer version of the framework that was released by Google in 2016. It is based on TypeScript, a superset of JavaScript, and offers a number of powerful features and optimizations for building high-performance web applications. Some of the key differences between Angular and AngularJS include:
- Architecture : Angular uses a component-based architecture, which makes it easier to break down complex applications into smaller, more manageable pieces. AngularJS, on the other hand, uses a directive-based architecture, which can be more difficult to scale and maintain over time.
- Performance : Angular offers a number of performance optimizations, including ahead-of-time (AOT) compilation and tree shaking, which can help to improve the speed and efficiency of web applications. AngularJS, on the other hand, can be slower and less efficient, particularly for larger applications.
- Language : Angular is based on TypeScript, a statically-typed superset of JavaScript, which offers a number of benefits over traditional JavaScript, including improved type safety and better tooling support. AngularJS, on the other hand, is based on plain JavaScript.
- Tooling : Angular comes with a powerful set of tools and utilities, including the Angular CLI, which makes it easier to create, test, and deploy web applications. AngularJS has a more limited set of tools and utilities, which can make development and deployment more difficult.
Overall, while AngularJS is still a powerful framework for building web applications, Angular offers a number of advantages in terms of performance, architecture, and tooling, which make it a preferred choice for modern web application development.
