Angular JS is an open-source JavaScript framework by Google to build applications. It is used in SPA(Single Page Application) projects. It provides additional attributes and makes the web pages responsive by extending the HTML DOM. It is known for its efficient framework and helps to create Rich Internet Applications(RIA). Developers prefer Angular JS as it allows them to write client-side applications using JavaScript in an MVC(Model View Controller) pattern. Applications developed through Angular JS are cross-platform compliant, and it automatically handles JavaScript code suitable for each browser. Angular JS helps in building large-scale, high-performance, easy-to-use, and easy-to-maintain web applications.
Angular JS is favored because,
- It lets you develop applications in a clean MVC pattern where the application logic is hidden from the user interface and separates layers.
- It supports dependency injection. It is a design pattern where you don’t need to hard code the dependencies within the component.
- It allows two-way data binding.
- It is easier to test applications built using the Angular JS framework as it is designed to test it from the start. It is easy to test its components from unit testing to end-to-end testing.
- It is an open-source, free-to-use tool.
Angular JS applications are a mix of JavaScript and HTML, and its JavaScript file is added to the HTML page to make use of it. Developers believe data binding is a potent tool in software development. It supports a two-way data binding model, which attracts many developers to use it. Angular JS supports the MVC pattern, and it has a model, view, and controller working separately. In one-way data binding, the data is taken from the model and inserted into an HTML element. There is no way to update the model from view, which results in data binding in one direction mainly used in classical template systems.
Two-way data binding in Angular JS applications leads to automatically synchronizing data between model and view components. It supports the idea of keeping logical implementations away from the user interface layer. This idea is achieved through data binding. The view is the projection of the implemented model, and the model is considered the master class or single source of truth in the application. Any modifications in the model result in view as it supports automatic synchronization and vice versa.
Angular JS makes use of expressions to bind the data of the application to HTML. Its numbers are similar to JavaScript numbers. Angular JS expressions can be written within HTML, whereas JavaScript can’t. Its expressions support filters and can contain variables, operators, and literals.
Angular JS is a structural framework that supports the development of dynamic web applications. Its everlasting helpful features for the development of applications attract the IT sectors towards it. Therefore, it paves the way for various job opportunities. To get hold of these benefits from Angular JS, you must first get familiar with them.
