What are the key distinctions between Angular and AngularJS?
                     
Angular Vs AngularJS
Various Javascript frameworks on the market now are specifically 
utilized for creating websites and mobile applications. Angular and 
AngularJS are the most well-liked frameworks currently available for 
front-end development.
But what differentiates them the most? Do they indeed vary from one 
another? You may be wondering about some of these things. To address 
these concerns, we have created an article that outlines the distinctions 
between Angular and AngularJS.
Let's examine the fundamentals of AngularJS and the Angular 
framework before we comprehend the concept of Angular Vs AngularJS.
What is the AngularJS Framework?
A structural framework for dynamic web 
applications is AngularJS. It enables you 
to use HTML as your template language 
and enhance HTML syntax to represent 
the components of your application 
succinctly and unambiguously.
Data binding and dependency injection in 
AngularJS allow you to write a lot less 
code than you would otherwise. And 
since everything takes place within the 
browser, any server technology can work 
well with it.

Top Features of AngularJS Framework
MVC (Model-View-Controller):
The MVC method is frequently used by the AngularJS framework when creating 
web applications. This design pattern is specifically intended to divide the 
presentation layer, the data layer, and the business logic layer into 
independent portions.
Data Model Binding:
The Instead of creating additional code to bind data, AngularJS makes it simple 
for developers to incorporate a few code snippets directly into the framework. 
Furthermore, it is simple to directly tie data from an HTML control to application 
data once you have added a few code snippets.
Top Features of AngularJS Framework
Writing Less Code:
Because it reduces the amount of code needed to manipulate the DOM, the 
AngularJS framework has proven to be quite helpful for Angular developers. 
Additionally, the developers do not need to write complex code structures 
when creating web applications.
Unit Testing:
Along with the AngularJS framework, the Google development team has also 
established a testing framework called "Karma." Karma's main function is to 
assist developers in creating a unit testing strategy for AngularJS apps.
Top Features of AngularJS Framework
Directives:
The AngularJS framework uses directives, which are dynamic markers on DOM 
elements that tell AngularJS to attach a certain behavior to the application. 
Additionally, it is in charge of handling or even altering the DOM element 
together with its children.
Not-Browser Specific:
Browser restrictions are not present in Angular applications. It can therefore 
operate effectively on all popular browsers, with the exception of Internet 
Explorer 8.0, including Chrome, Firefox, Safari, IE8, and Android.
Top Features of AngularJS Framework
Dependency Injection:
Dependency injection makes it simple for AngularJS developers to 
design and construct applications more quickly. Additionally, it makes 
it simpler to test an application. It enables you to request your needs 
rather than having to find or create them on your own.
AngularJS Architecture
The controller interacts with the data model objects and responds to user 
Controller input. After receiving and validating input, the controller carries out business 
actions that change the state of the data model.
View A data presentation that takes place in a specific format as a result of the controller's choice to do so. They are template systems based on scripts.
Model The model is in charge of managing application data. It updates itself in response to the view's request and the controller's directives.
Pros and Cons of AngularJS
PROS CONS
● Two-Way Data Binding ●  JavaScript Support Mandatory
●  DOM Manipulation ●  Inexperience With MVC
●  Improved Server Performance ●  The Scope
●   Faster Application Prototyping ●  Other Complex Feature
●  Responsive Web App ●  Possible Time Consumptions
●  Highly Testable Product ●  Difficult Learning
What is Angular?
Angular is a JavaScript framework 
that is open-source and developed 
in TypeScript. It is maintained by 
Google, and its main use is to 
create single-page applications.
Angular is a framework with 
undeniable benefits that also give 
programmers a uniform framework 
to work with. It gives users the 
ability to make huge apps in a 
manageable way.

Top Features of Angular
MVC Architecture:
MVC stands for Model-View-Controller. Data management for your 
application is normally handled by Model, while data display is often 
handled by View. The Controller's main responsibility is to act as a mediator 
between the View and the Model.
Two-Way Data Binding:
In the Angular framework, the View layer stands in for the Model layer and 
maintains perfect synchronisation. As a result, whenever the developer 
makes a subsequent update to the model, the users will automatically see it 
in the view model. As a result, it cuts down on important development time.
Top Features of Angular
Few Code Framework:
Angular is regarded as a low code framework when compared to other 
front-end frameworks. Simply put, the MVC layers do not require the 
developers to build separate code to join them.
Angular CLI (Command Line Interface):
In AngularJS development services, the Angular CLI is essential. It has a 
number of built-in features that make the application more responsive, 
such as SCSS support or routing features.
Some of the standard Angular CLI is ng new, ng generate, ng serve, Test, 
Lint
Top Features of Angular
TypeScript:
Angular follows completely to TypeScript language. Angular provides 
developers with a durable experience because to its active support of 
TypeScript. Additionally, finding faults quickly and cutting down on 
development time are advantages for developers.
Directives:
Directives, a crucial component of Angular apps, let programmers build unique 
HTML tags, which are typically used as unique widgets. These can be used by 
developers to embellish behavior-driven features. Developers using Angular can 
manipulate the DOM effectively based on the requirements of the project.
Angular Architecture
Angular Architecture
● Modules:
A root module called "AppModule," which is required for all Angular applications. All 
that is necessary to launch the program is the bootstrap phrase.
● Components:
For the Angular project to be constructed, at least one component is necessary. Two 
key elements, the root component, and root component link the component 
hierarchy to a page document object model (DOM).
● Templates:
Simply combining HTML with Angular markup, which may swiftly modify HTML 
components before they are displayed, is the main function of an Angular template.
Angular Architecture
● Metadata:
The functionality that provides information to Angular for class processing is 
metadata. In short, it is used to decorate the class so that it may be configured to 
perform as desired.
● Data Binding:
In order to facilitate communication between a template and the corresponding 
component, data binding is crucial.
● Directives:
As a directive with a template, Angular components can be summed up in this 
way. The foundation of each Angular project is its directives.
Angular Architecture
● Services:
It is necessary to construct service classes that aren't linked to any 
particular view but play a crucial part in the presentation of logic or data. 
The service class definition comes before the @Injectable decorator.
● Dependency Injection:
You may keep your component classes compact and effective by using 
dependency injection (DI). Instead of relying on the services to obtain 
data from a server, validate user input, or log straight to the console, DI 
uses the services.
Pros and Cons of Angular
PROS CONS
●  Google-Supported framework ●  Limited SEO Options
●  Third-Party Integration Support ●  Difficult to Learn
●  Faster Load Time ●  Time Consuming
●   Customizable Framework ●  Application Scaling
●  Dependency Injection ●  Not Good For Simple Web App
