There are a variety of ways to validate parameter entry, in PowerShell.
Instead of writing code within functions or scripts to validate parameter values, these ParameterAttributes will throw if invalid values are passed.
ValidateSet
Sometimes we need to restrict the possible values that a paramet...
// Fetches the value of $_GET['id'] and returns 0 if it does not exist.
$id = $_GET['id'] ?? 0;
// This is equivalent to:
$id = isset($_GET['id']) ? $_GET['id'] : 0;
// Coalescing can be chained: this will return the first defined value out of
// $_GET['id'], $_POST['id'], and 0.
$id = $_GE...
Sometimes you want to switch off all previously registered listeners.

Instead of defining URL endpoints for each data resource, in GraphQL you define a single endpoint that accepts GraphQL queries. Unlike traditional database query languages, GraphQL Query Language (GQL) is a projection of data returned by a root level query. The GraphQL schema will define the data mo...

To understand Dependency Inversion Principle (DIP) we need to clear concept about Inversion Of Control(IOC) and Dependency Injection(DI). So here we discuss all about the terms with Dependency Inversion Principle (DIP).

Introduction
SRP can be defined as “a class handles only one responsibility”. This is a very short definition for something influential on to the other principles of S.O.L.I.D. I believe that if we get this right, it will have a positive knock-on effect on the upcoming principles, so let’s get star...
Here we give an example of ISP violation and then refactor that violation. Without talking unnecessary things let's jump into the code.
ISP violation :
