WHAT IS ANGULAR? ITS DIFFERENCES WITH ANGULARJS
1. What is Angular?
Angular is a web application development framework built and maintained by Google, written in TypeScript. Angular is part of the JavaScript platform for building single-page web applications (Single Page Applications – SPAs).
Angular provides a component-based approach, where each component represents a part of the user interface and it can contain its JavaScript, HTML, and CSS code. These components can interact with each other through services, and the entire application is managed through a virtual database called the “application graph”.
Angular provides a variety of features such as two-way data binding, dependency injection, routing, and many other development tools that make building web applications easier and more efficient. more effective.

2. Angular development process
- AngularJS (2010): AngularJS was developed by Misko Hevery and Adam Abrons at Google. AngularJS is a JavaScript framework that Google developed to help build dynamic, single-page web applications (Single Page Applications – SPAs).
- Angular 2 (2016): After a period of development and learning from experience with AngularJS, Angular 2 (commonly known as Angular) was introduced in September 2016. Angular 2 is not just an updated version of AngularJS but also a completely new version with a different architecture and syntax. Angular 2 is completely rewritten in TypeScript and has many improvements in performance, testability, and module system.
- Angular 4, 5, 6,… (2017-2018): Angular continues to update with new versions. These versions often bring performance improvements, features, and bug fixes. Angular uses a regular release cycle and ensures backward compatibility with previous versions.
- Angular 7, 8, 9,… (2018-2019): As with previous versions, new versions of Angular continue to bring improvements in performance, features, and bug fixes. Angular also focuses on optimizing the size of the application and improving the development experience.
- Angular 10, 11, 12,… (2020-2021): New versions of Angular continue to introduce improvements and new features, as well as bug fixes. Google and the Angular developer community both contribute to the maintenance and development of the framework.
- Angular 13: Deep integrations, performance, and security make Angular 13 an important step forward.

3. Basic features of Angular
- Component-Based: Angular uses a component architecture, where each part of the application is represented as an independent component. Components are user interface building blocks and contain their own JavaScript, HTML, and CSS code.
- Two-Way Data Binding: Angular supports two-way data binding, allowing automatic synchronization between data and the user interface. Changes in data will immediately reflect on the interface and vice versa.
- Dependency Injection: Angular uses a Dependency Injection (DI) system to manage and organize application components. This reduces code complexity and creates code that is easy to test and reuse.
- Routing: Angular provides a built-in routing system that allows switching between pages and components in the application without reloading the page.
- Forms: Angular provides a powerful module to manage and process forms. This includes user control, data validation, and user interaction.
- Modules: Angular applications are organized into modules, helping to manage the source code and functions of the application in an organized way.
- TypeScript: Angular officially uses TypeScript, a superset of JavaScript with static data types and many other features, which help control errors, improve performance, and make code more readable and efficient.
4. Are Angular and AngularJs the same?
Angular and AngularJS are two web application development frameworks from Google, and they have important differences in architecture, syntax, and features. Some key differences between AngularJS (commonly known as Angular 1.x) and Angular (commonly known as Angular 2 onwards).

- Architecture and language:
- AngularJS: Uses JavaScript or an improved version of it called TypeScript.
- Angular: Officially uses TypeScript, a superset of JavaScript with static data types and many other features.
- Ingredients and directives:
- AngularJS: Use ng-controller, ng-model, ng-repeat and other directives to create and manage components in the application.
- Angular: Use components and directives to create application structure. There is a component-based architecture model.
- Dependency Injection:
- AngularJS: Does support Dependency Injection but is not a major part of the framework.
- Angular: Uses Dependency Injection which is powerful and is an important part of how Angular manages and organizes source code.
- Routing:
- AngularJS: Has routing but not built-in, often requires using additional modules like ngRoute.
- Angular: Has a built-in routing system, helping to conveniently manage and navigate between pages.
Due to the huge difference between AngularJS and Angular, people usually do not switch directly from one framework to another but instead often rebuild the application from scratch when wanting to switch from AngularJS to Angular.
5. Should I learn Angular or AngularJs?
Deciding whether to learn Angular or AngularJS depends on your specific goals and context.
- AngularJS: Learn if you are working on a legacy project using AngularJS or want to understand the history and origins of Angular.
- Angular: A good choice if you’re just starting out or want to update your knowledge with a modern, continuously supported and developed framework.

WHAT IS WEB3? ENTER THE NEW WORLD OF TECHNOLOGY WITH WEB3
What is Web3?
Concept
Web 3.0 is the third version of the Internet, an improvement over the current Web 2.0 Internet. This is a trend in technology whose goal is to build a decentralized online environment in which data management and control is transferred from centralized organizations to individual users. Web 3.0 is built with artificial intelligence (AI), machine learning and semantic web (Semantic Web), and uses blockchain security systems to keep information safe and secure.

Progressive development
- Web1 (1990s): Web1 was the first stage of the Internet, users could only read and view content on websites without the ability to interact or contribute.
- Web2 (Late 2000s – Present): Web2 is the current stage of the Internet, highlighted by interaction on social networking platforms. This is accompanied by strong growth in mobile applications, online advertising, and revenue from user data. Services such as Gmail, Google Maps, and mobile applications from the App Store and Google Play are typical of Web2.
- Web3: Web3 is a growing trend, characterized by a focus on transparency, decentralization, and user rights.

Structure of Web3
Web3 operates on a series of new technologies and in particular the integration of blockchain and decentralized applications.
- Blockchain: Blockchain is the backbone of Web3. This is a distributed and immutable database system where data is stored in interconnected blocks. Blockchain provides transparency, security, and decentralization of transactions and data.
- Smart contracts: On the blockchain, smart contracts are pieces of code that automatically operate when conditions are met. They help automate trading processes and execute agreements without third-party intervention.
- Decentralized Applications (DApps):
+ Front-end: The user interface is built using a common web programming language.
+ Back-end: Interact with blockchain through protocols and smart contracts, store data on decentralized storage systems like IPFS. - Decentralized resources: Services such as storage, computing, and networking can be managed decentralized through systems such as IPFS and other projects. This increases flexibility and reduces dependence on central services.

Advantage
- Decentralization and transparency: Web3 reduces dependence on central organizations and creates a more decentralized environment. Blockchain and smart contracts help increase transparency and fairness in transactions.
- Data privacy and control: Users have greater control over their personal data. Decentralized identity systems help prevent insufficient information collection.
- Flexibility and increased interoperability: DApps and decentralized markets create an environment where users can interact directly and transact without third-party intervention. Using tokens and digital assets increases flexibility in managing and sharing value online. This opens up many new opportunities for users.
- Highly safe and secure: Using blockchain to store data and smart contracts to perform transactions, Web3 reduces security risks such as cyber attacks and unauthorized access to data.
Disadvantages
- Not yet scalable: Some Web3 technologies, especially blockchain, may have difficulty scaling to handle large numbers of transactions.
- Large energy consumption: Some blockchains, such as Bitcoin and Ethereum, can consume large amounts of energy, causing environmental concerns. Web3 requires technical devices with higher technical and features. So currently only a limited number of people can access web 3.0.
- Complex functionality: Web3 creates challenges for users due to the complexity of blockchain technology, smart contracts, and new concepts such as DeFi, NFTs. Some applications and user interfaces in the Web3 space may not be intuitive and easy to use enough, making the user experience difficult for those without blockchain experience.
Web3 applications
- DeFi (Decentralized Finance): Represents a new completely decentralized financial system based on blockchain technology and smart contracts. The goal of DeFi is to eliminate dependence on traditional financial institutions, such as banks and investment funds, by providing financial services that people can use directly without intervention. third party cards.
- NFTs (Non-Fungible Tokens): a type of token that represents ownership of a special asset and cannot be replaced by any other token. This means that each NFT is unique and has its own value, and cannot be replaced or equivalent to any other token of the same. NFTs are often used to represent ownership of digital works of art, video game items, virtual elements in cyberspace, and many other types of digital assets.
- DAOs (Decentralized Autonomous Organizations): They are decentralized organizations built on the blockchain platform, operating based on smart contracts and decisions made through the decentralized process of the member community. DAOs can be applied in many areas, from financial management to strategic decisions, project management, and even creative and content management in the arts industry.
- DApps (Decentralized Applications): DApps use blockchain and smart contracts to provide services without the intervention of a third party. For example, Uniswap is a decentralized DApp for cryptocurrency exchanges, and CryptoKitties is a DApp in the field of NFTs and blockchain games.
