Description

Introduction of Forms in Angular

Forms are a core component of web applications, allowing users to interact with data. Angular provides two powerful approaches for managing forms: Template-Driven Forms for simple use cases and Reactive Forms for more complex, dynamic interactions. This training explores both methodologies, covering form validation, data binding, dynamic form creation, and best practices to help developers create robust and scalable Angular applications.

Prerequisites

• Basic knowledge of HTML, CSS, and JavaScript
• Familiarity with Angular components and modules
• Understanding of TypeScript and Angular CLI
• Basic experience with event handling and data binding in Angular
