What is ngFor directive in Angular?

The ngFor directive in Angular is a powerful tool for creating dynamic lists in your application. It is a built-in structural directive that allows you to iterate over a collection of data and generate HTML elements for each item in the collection.

With ngFor, you can easily display a list of items from an array, objects, or any iterable object in your Angular templates. This directive is especially useful when you need to display a dynamic list of items, such as a list of users, products, or any other type of data.

The syntax for using ngFor is simple and easy to understand. You can use it on any HTML element to repeat that element for each item in the collection. Here’s an example of how to use ngFor to display a list of users in your Angular component:

“`html

• {{ user.name }}

“`

In this example, the ngFor directive iterates over the “users” array and creates a new list item for each user in the array. The “let user of users” syntax is used to define a local template variable “user” for each item in the “users” array, which can then be used to display the user’s name using interpolation.

ngFor also provides a variety of useful features, such as tracking changes to the collection and updating the DOM efficiently. It also supports index tracking, allowing you to access the index of each item in the collection.

In summary, the ngFor directive in Angular is a handy tool for creating dynamic lists in your application. It simplifies the process of iterating over a collection of data and generating HTML elements for each item, making it easier to build dynamic and interactive user interfaces in your Angular applications.
