angular 18 has introduced several new features and improvements that enhance the framework's capabilities and developer experience. in this tutorial, we will cover the following aspects of angular 18:

1. *new features in angular 18*
2. *setting up an angular 18 project*
3. *creating a simple application*
4. *using standalone components*
5. *improved signals and reactivity*
6. *conclusion*

1. new features in angular 18

angular 18 builds on the previous versions and includes several notable features:

**standalone components**: components can be created without needing to be declared in an ngmodule, simplifying the structure.
**improved signals**: angular's reactivity model has been enhanced, making state management easier and more efficient.
**enhanced cli**: the angular cli has received updates for better performance and new commands.
**angular devtools**: improved support for debugging and profiling angular applications.

2. setting up an angular 18 project

to get started with angular 18, first, ensure you have node.js and npm installed. then, you can use the angular cli to create a new project.



once the application is running, you can access it at `http://localhost:4200`.

3. creating a simple application

let's create a simple application that displays a list of items and allows users to add new items.

step 1: generate a standalone component

using angular 18, we can generate a standalone component without needing to declare it in an ngmodule.



step 2: update the standalone component

edit the generated `item-list.component.ts` file:



4. using the standalone component in the app

edit the `app.component.ts` to use the `itemlistcomponent`:



5. improved signals and reactivity

in the above example, we used signals to manage the state of our items. signals are a powerful way to handle reactivity in angular, allowing for fine-grained control over state changes.

here’s a brief overview of how signals work:
