What is data binding? Which type of data binding does Angular deploy?

Question

Sharp Mind · Answer

Data binding is a fundamental concept in web development that establishes a connection between the UI (User Interface) and the data model of an application. It enables synchronization between the two, ensuring that any changes made to either the UI or the data are reflected in real-time. There are generally two types of data binding: one-way binding and two-way binding. One-way binding involves updating the view (UI) when the model changes, whereas two-way binding allows for both the view and the model to update each other. Now, specifically focusing on Angular, which is a popular JavaScript framework maintained by Google, it primarily deploys two-way data binding. Angular's two-way data binding enables automatic synchronization of data between the model and the view, making it easier to develop dynamic and interactive web applications. For instance, in Angular, you can use directives like `ngModel` to establish two-way data binding between an input field in the UI and a corresponding variable in the component's data model. Here's a simple example in an Angular template: Hello, {{ name }}! In this code snippet, any changes made in the input field will instantly update the `name` variable in the component class, and vice versa. This real-time synchronization is powered by Angular's two-way data binding mechanism. Overall, Angular's implementation of two-way data binding simplifies the development process by eliminating the need for manual DOM manipulation and ensuring that the UI and data stay in sync effortlessly.
