Angular is an agile web application framework which allows you to develop complex web applications. It presents various design patterns and tools to build complex projects. It is easy to understand the code written by an Angular developer. This is a full-featured framework that offers features like interfaces and static typing. It has no learning curve and can be used by developers of all levels. It also helps you to implement server communication and routing within your applications.

Angular is written in the TypeScript language, which is a superset of JavaScript. This language can be used to prevent common errors while typing code. Angular’s TypeScript enhancement is essential for enterprise-scale applications. The ‘TypeScript first’ policy is controversial, with complaints about its use in development communities. While TypeScript is a powerful language, it should not be used as a replacement for JavaScript.

The first step in learning Angular is to create a project. You need to create a component hierarchy in your project. The root component is a parent component which connects the component hierarchy to the DOM. Each component defines a class and a template for the corresponding HTML page. Then, you need to add decorators to your components. You can use a single decorator or a combination of decorators.
