Functions in PowerShell allow reusable blocks of code to be defined and provide an interface between code and users. Functions can define parameters and parameter types, and even provide help documentation like cmdlets. Advanced functions gain additional capabilities by using the [cmdletbinding] tag, working more like native PowerShell cmdlets through access to common parameters.

2. Functions in PowerShell
• Functions provide the interface between your code and the user.They
can define parameters, parameter types, and even provide help,
much like cmdlets. A block of code may be contained within a
function for easy re-use.To create a function, call the function
keyword followed by a name for the function, then include your code
inside a pair of curly braces
Function <function_name> (function_parameters) { <function_body> }

3. Advanced Functions in PowerShell
• Advanced functions - advanced functions gain access to common
Windows PowerShell parameters and other stuff that makes the
function work like aWindows PowerShell cmdlet.The secret? It is the
use of the [cmdletbinding] tag.
