As new developments take place in technology and debugging, upgrades are necessary. Some applications are easier to upgrade, but there are many ways to make upgrades easier for those that are not.
For doing so, you must prepare and align AngularJS applications with Angular before beginning the upgrade process. These preparation steps make the code more decoupled, more maintainable, and better aligned with modern tools used in development. This adds to the improvement of the existing AngularJS applications.
Client side development has been revolutionized with the introduction of front end frameworks such as AngularJS and Angular. Both of these frameworks follow the Model-View-Controller (MVC) architecture that enables developers to improve code organization and enhance the user experience.
While AngularJS is an older version with a more complex structure, Angular is a more powerful framework that provides better support for modern web development technologies. Its modular architecture and dependency injection allow for faster and more efficient development. Full Stack Development courses cover both of these frameworks along with other web development tools and technologies, making it easier for developers to choose the right framework for their projects.
The main difference between AngularJS and Angular can be seen in the language used to write the code. While AngularJS uses JavaScript, Angular uses Typescript. This makes the development process easier for developers as TypeScript is a superset of JavaScript. Additionally, using TypeScript allows developers to use features such as classes, interfaces, and modules which helps in developing more efficient and maintainable code.
What is AngularJS?
AngularJs is a Javascript open-source framework used in the front-end to develop SPAs (single-page web applications). It provides a better for developing web applications. What it does is changes the HTML from static HTML to dynamic HTML.
AngularJS has key features like dynamic binding and dependency injection. These features eliminate the need for code that needs to be written otherwise. AngularJs are presently growing rapidly, and because of that, there are different versions of AngularJs.
Though they may sound very similar, Angular is very different from AngularJs.
What is Angular?
Angular is an open-source project which can be freely accessed, used, and changed by anyone. It is a development platform built on TypeScript. Angular offers:
- A component-based framework that can be used for building scalable web applications
- A collection of libraries that cover a plethora of features: including routing, forms management, and client-server communication- all very well integrated
- A suite of all the developer tools that you need to develop, build, test, and update your code
With Angular, it can scale up from single-developer projects to enterprise-level applications. Angular makes updating as easy and less complex as possible to gain access to the latest developments with minimal effort. As a result of this diversity, the ecosystem comprises a diverse group of over 1.7 million people who help develop, curate content and run the platform.
Key differences between both versions
1. Components
While AngularJS uses JavaScript, Angular uses TypeScript. The TypeScript used in Angular is a superset of ES6. ES6 has backward compatibility with ES5.
Since AngularJS is based on JavaScript, it uses terms of scope and controllers. Angular, on the other hand, uses a hierarchy of components.
2. Use of Directives
Angular and AngularJS use Directives but how they use them makes the difference. Angular has only standard Directives. AngularJS has a pack of Directives. You have to be very careful while using the Directives.
For example, if you have to create a two-way binding in AngularJS, you will use the ng-model, and for making the one-way binding, you will use ng-bind.
But in Angular, only the model is present. To make a difference, you can use the symbols for one-way binding as:” [],” and for two-way binding as:” [()].”
3. Architecture
In Angular JS, the framework has a model-view-controller (MVC). The MVC acts as the central component. It is responsible for managing data, logic, and rules and expressing how the applications behave. Here is what MVC does:
Model: The model is the place where management of all data is present.
View: This is the output presented after reviewing the information in the model.
Controller: The controller is the site that receives the input and converts it to commands. It is then sent to the model and viewed.
The components for Angular are directives with templates. The two kinds of messages in Angular are
Structural directives: Structural directives are responsible for altering the layout of DOM by replacing its elements.
Attributive directives: Attributive directives change how the DOM behaves and appears.
4. Mobile support
While AngularJS does not provide support to mobiles, Angular supports mobile phones.
5. Performance and Speed
Since Angular JS has a two-way binding feature, it ultimately reduces efforts and time of construction, making it better and faster. For Angular, the framework is upgraded to a better structure to improve performance and speed.
Tool support
For support tools, Angular JS relies on third-party tools like IDE and WebStorm. Angular uses the Command Line Interface (CLI) as a support tool to reduce the time when creating applications- making it more efficient.
Angular JS Vs Angular
| Criteria | Angular JS | Angular |
| Architecture | It supports MVC design. | Uses components and directives with a template. |
| Language | It is written in JavaScript | It is written in TypeScript: a superset of ECMAScript 6 (ES6) |
| Expression Syntax | For binding of image, property or event, the developer needs to remember the right ng directive. | It uses “()” for event binding and “[ ]” for property binding |
| Mobile Support | Does not support mobile | Supports mobile |
| Dependency Injection | It does not use dependency injection | It uses a hierarchical dependency injection system with a unidirectional tree-based change detection |
| Structure | It is less manageable | It has a better structure and it is easier to create and maintain large applications. |
| Speed | The effort and time is reduced due to its feature of two-way binding | Angular 4 is the fastest version yet. |
Conclusion
Both Angular JS and Angular have their own pros and cons. They both are different from each other in various ways as listed above. If you want to learn these technologies, you can take Full Stack Development courses which will cover both these technologies along with other web development tools and technologies.
About 1,022,394 live websites are today using Angular JS and there are an additional 3,098,583 sites that get used as Angular JS historically. These numbers clearly state that Angular JS has become increasingly popular today. There are multiple factors contributing to its popularity such as its features and its ability to develop reactive and responsive web applications with great ease.
On the other hand, Angular is comparatively much more efficient when it comes to performance as it provides developers with a complete suite that can be used from testing to hybrid apps and to animations. Angular is used by 0.4% of all the websites which can be considered a high number. It is also used by many popular websites like Netflix, Forbes and Gmail.
In conclusion, Angular JS and Angular have their own unique features that have led to their increasing popularity in the web development world. Based on your needs, any of them can be chosen as they provide different approaches to approach web development. In order to get a better understanding of these technologies, taking a Full Stack Development course is highly recommended. With this, you will be able to develop the skills required for proficient web development.
