Splatting allows you to pass parameters to a function as a hashtable. This can make your code more readable when you have a lot of parameters to pass to a function. It also allows you to build the parameters dynamically.

To use splatting, create a hashtable with the parameter names as the keys and the parameter values as the values. Then, pass the hashtable to the function using the `@` operator.

You can also use splatting with arrays, where the array values are passed to the function as positional parameters.

In a function, you can use the $PSBoundParameters automatic variable to access the parameters that were passed to the function. This allows you to modify and extend the given parameters before passing them to another function.
