A "Parameterized pipe" in Angular refers to a pipe that accepts one or more parameters to customize its behavior. Pipes in Angular are used to transform data before displaying it in a template. They can be chained and combined, and they can take parameters that allow you to fine-tune the output.
For example, the built-in DatePipe can be parameterized to format a date object into various string formats. Here's how you might use it in a template:
{{ myDate | date:'fullDate' }}
In this example, 'fullDate' is a parameter passed to the DatePipe to specify how the date should be formatted. The DatePipe can take other parameters for different date formats, such as 'shortDate', 'mediumTime', etc.
Another example is the DecimalPipe, which formats a number as text. You can specify the format like so:
{{ myNumber | number:'1.0-2' }}
Here, '1.0-2' is the parameter that tells the DecimalPipe to format the number with at least one digit before the decimal point and between zero and two digits after the decimal point.
Parameterized pipes are not limited to the built-in pipes; you can also create custom pipes that accept parameters. When defining a custom pipe, you can specify additional arguments after the value to be transformed, and these argument...
