AngularJS is a JavaScript-based open-source front-end web application framework mainly maintained by Google and by a community of individuals and corporations to address many of the challenges encountered in developing single-page applications. The JavaScript components complement Apache Cordova, a framework used for developing cross-platform mobile applications. It aims to simplify both the development and the testing of such applications by providing:
- framework for client-side model–view–controller (MVC),
- model–view–view-model (MVVM) architectures,
- along with components commonly used in rich Internet applications.
When Did Angular Start?
In 2014, the original AngularJS team began working on Angular (Application Platform). The AngularJS framework works by first reading the HTML page, which has additional custom tag attributes embedded into it. Angular interprets those attributes as directives to bind input or output parts of the page to a model that is represented by standard JavaScript variables. The values of those JavaScript variables can be manually set within the code, or retrieved from static or dynamic JSON resources.
AngularJS is built on the belief that declarative programming should be used to create user interfaces and connect software components, while imperative programming is better suited to defining an application's business logic. The framework adapts and extends traditional HTML to present dynamic content through two-way data-binding that allows for the automatic synchronization of models and views. As a result, AngularJS de-emphasizes explicit DOM manipulation with the goal of improving testability and performance.
Angular implements most of its features as directives attached to HTML elements (HTML tags). These directives are markers on a DOM element that tell Angular to attach a specified behavior to that DOM element or even transform the DOM element and its children. angular produces three types of directives: Components, structural directives, and attribute directives.
Technical - TLDR
Components are high-level directives with templates; they define areas of responsibility in the user interface, like a search box with results area.
Structural directives change the structure of the DOM layout by adding and removing DOM elements. Examples include *ngIf , which removes an element if a given expression evaluates to false , or *ngFor , which repeat an element for each item in an array .
Attribute directives change the appearance or behavior of an existing element without changing its structure. For examples, ngClass lets class values be added dynamically based on expressions, while ngStyle lets inline styles be added dynamically based on expressions.
Angular also comes with several services that can be injected into web applications:
- HTTP requests ( $http ),
- browser location information ($location),
- animations ($animate),
- logging ($log),
- and internationalization ($locale).
These services make it easier to build single-page applications by giving developers access to helper functions that perform common tasks like accessing remote data or setting up event handlers." angular was originally released in October 2010 as angularJS .

What is a simple comparison of AngularJS vs ReactJS
There are a lot of factors to consider when choosing a web development framework for a startup. React and Angular are two of the most popular options, and each has its own strengths and weaknesses.
React is a JavaScript library that was created by Facebook in 2013. It's used for building user interfaces, and it's one of the most popular options for front-end development. One of the key benefits of React is that it's easy to learn and use. react is also very efficient, which makes it perfect for startups that need to move quickly.
Angular is a web development framework that was created by Google in 2010. It's used for building single-page applications, and it's one of the most popular options for front-end development. Angular is a bit more complex than React, but it offers a lot of powerful features. One of the key benefits of Angular is that it's easy to maintain.
Both React and Angular are excellent choices for startups, but there are some key differences to consider. If you're looking for something that's easy to learn and use, then React is the better option. However, if you're looking for something that's more powerful and easy to maintain, then Angular is the better choice.
