Parameterizing pipes

A pipe can take parameters as well. We can pass parameters along with the pipe. A parameter is separated with a colon symbol (:) after the pipe:

{{appValue | Pipe1: parameter1: parameter2 }}

Let's quickly build a simple example of a pipe to see it in action. Here's an example of DatePipe with the MM-dd-yyyy parameters:

{{today | date:'MM-dd-yyyy' }} 

One more example of a pipe with parameters is given as follows:

{{salary | currency:'USD':true}}

Let's analyze the preceding code snippet in detail:

1. We passed USD as a parameter to CurrencyPipe, which will tell the pipe to display the currency code, such as USD for the US dollar and EUR for the euro.
2. The true parameter stands for displaying the symbol of the currency ($). By default, it's set to false.

Let's see them in action with complete code for the component...
