    The complete Guide to Angular: Everything You Need to Know

    Angular lies within the JavaScript ecosystem and is helpful in most web development projects. Nearly 30% of the developers use AngularJS for building up their user interfaces. Professional developers use it to develop versatile web applications. It has countless features to scale up and optimize the code for better performance. 

    Angular material is compatible with both IOS and android devices making it more usable and beneficial for the developers. They can get more by paying less, which is the most exciting thing about using the AngularJS framework.

    We also have a curated AngularJS online course for all the experienced and beginner developers that will help them to innovate different web applications. 

    What is Angular: The Story Behind AngularJS and Angular 2+

    Angular is the most commonly used framework that helps to develop front-end user interfaces. The two major variants of Angular are- 

    Angular 2+:  This version was released back in September 2016. It was developed to fulfill the increasing demands of developers in web technology. This version and the previous version have a drastic change that the developers could not easily migrate. It required a lot of changes in the syntax which was impossible to have. 

    AngularJS: This was the basic version of Angular developed in 2010. It allows the developers to convert their HTML documents into dynamic projects. Users can create various web pages with innovative and elementary designs. 

    Given below is a hierarchy of dependencies followed by AngularJS.

    Angular Versions History: Angular 2-9

    The angular framework is divided into AngularJS and modern versions. Each one of us is already familiar with AngularJS. So, let’s now look at the contemporary Angular version one by one.

    Angular 2: had significant changes from the previous version and was written in Typescript. It has got an ib-built compiler and a component-based architecture. 

    Angular 4: The fourth version of Angular introduced the Angular CLI for its users. This interface was the central element of the framework, and the developers can now render their pages without the browser.

    Angular 5-6: These versions combined the CLI and the compiler to make it more optimized. It had different updated tools to migrate from one version to another.

    Angular 7: With angular 7, the CLI became more functional and efficient. It was improved more along with its documentation.

    Angular 8: This update had only two differences: Ivy renderer and bazel. 

    Angular 9: This is the latest update as of now. It was introduced in February 2020. You can look at its documentation that includes all the details of the deprecations. 

    This was a short description of the Angular versions. You can refer to what is web development course for more details. 

    Angular Tools and Setup

    Angular development tools are a platform used to create and write code in the application in Angular. Some of the Angular tools useful for the Developers are as follows- 

    1. Node Package Manager (NPM)- npm is an essential module in an angular project. The project contains multiple files divided and stored in npm packages. It makes the code handy where the developers need to install only the valuable packages.
    2. Angular CLI- Angular CLI is the other important module used to run angular. It is a command-line interface ensuring that your application uses efficient code and syntax to make it more readable and error-free. 
    3. HTML and CSS- Html and CSS are used to create an interactive user interface with basic functionalities that come with rendering the web pages. 
    4. TypeScript- Since angular is a TypeScript language, every developer must be familiar with the language, and it is again an important tool to work with.

    Angular setup is a go-to process involving fewer steps than any other framework. To start the first angular project, a developer needs to perform the following points.

    • Setting up the environment means that a developer must create the local variables to start the work. These variables can be accessed globally.
    • Creating a workspace- Create a new angular workspace that contains all the files and folders within the project. You can use the Angular CLI interface for this. 
    • Serve the angularmaterial application- Now, start the application and use the “ng serve --open” command to open a browser running at 4200 port. 
    • Make the desired changes- use the selected angular bootstrap components and create attractive interfaces. 

    Pros and Cons of AngularJS

    The AngularJS framework has pros and cons, similar to a coin with two sides. The developers who are used to the AngularJS framework or its regular users know what Angular can do. It becomes an easy task for developers to use the framework more efficiently when dealing with both the pros and cons.

    First, let’s discuss the advantages of the AngularJS that have contributed to the technology and developed into advanced architecture and the best framework to rely upon. Some of the exceptional characteristics of the angular material are as follows.

    • Efficient in Problem-solving- Angular provides efficient problem-solving support by resolving productivity issues. It has two parameters- Dependency injection and its services. The former is used to create different objects dependent on the existing things. At the same time, the latter works to make your code more readable and cleaner.
    • Component-based Architecture- Angular has its hierarchy of components, known as a component-based architecture. Its features impart their respective functionalities, making AngularJS a helpful framework.

    What is Angular: The Story Behind AngularJS and Angular 2+

    • DOM Manipulation- DOM stands for Document Object Model, which defines the structure of angular bootstrap. The developers can directly keep a check on the DOM for all the ongoing updates available. 
    • Two-way Data Binding- The two-way-data binding feature of angularcli controls all the changes made within the model. A change in the model is reflected in UI as well.
    • Lightweight Web Application- The Angular framework earlier had an issue of significant size that restricts fast loading. The latest version has improved functionality, making it a lighter web application than its other models. This is because of the two main factors- 
    • Load Modules- The developer’s code in the Angular framework identifies the components used by them. It then reduces the loading effect, thereby increasing speed. 
    • Ivy Renderer- Ivy Renderer is responsible for making small code packets to ensure fast processing. 
    • Material design Library- Angular has an excellent angularmaterial library with numerous attractive designs. These designs help the developers to create valuable and responsive user interfaces.
    • Readable Code- Angular has the structural elements that make it a perfect tool for a front-end developer. It has modules and components performing individual tasks. AngularJS makes it possible for the developers to follow different model architectures such as MVC or MVVM. These models make the code reusable and hence eliminate the redundant code.

    Angular has some drawbacks that the developers must consider before and while using the application. So, here are some of the cons of angular.

    • Steep curve- The language has a steep learning curve as a developer familiar with JavaScript would find it hard to learn Angular speedily. In contrast, they would discover ReactJS to be simpler and easier to implement. It has many topics to be covered, making it difficult to adapt.
    • Complex software- AngularJS is one of the most complex software developers. Because of its vast number of components, it is quite challenging to manage. It also has various third-party libraries with different syntaxes. 
    • Skillful developers- Angular has features that may be challenging for non-experienced developers to grasp and use instantaneously. Instead, it may require expert developers to work efficiently with them. These features include MVC, directives, the latest in-built libraries, and dependencies. 
    • Time-consuming legacy systems- Angular and AngularJS has minor differences in their working method. Migrating the legacies of Angular to AngularJS is a time-consuming process that increases the loading effect on the processor.


    All the non-developers interested in Angular can get the best expert guidance and help through our KnowledgeHut’s AngularJS online course. This article had a detailed description of AngularJS, its components, and some pros and cons. Do check out the courses for better clarity.
