Angular is an open-source, JavaScript framework written in TypeScript. Google maintains it, and its primary purpose is to develop single-page applications. Angular 17 introduces a new block template syntax that provides powerful features with simple, declarative APIs1. This new syntax allows for control flow, lazy loading, and more. For example, the new @for and @if blocks simplify the formulation of control flow in templates2.

Angular 17 introduces the View Transitions API, a feature that enables seamless and captivating animations when transitioning between pages within your application1. For instance, you can create a fade-in animation when transitioning from the product list page to the product details page.
