PowerShell is a powerful tool that can be used to manage many tasks. One of the tasks that PowerShell can be used to manage is creating functions. Functions are a way to group related tasks into one place and make them easier to use. One way to create a function is by using the New-Object cmdlet. The New-Object cmdlet allows you to create a new object, which will have the following properties: Name: The name of the function The name of the function Type: The type of function you want to create (module, script, or class) The type of function you want to create (module, script, or class) Parameters: A list of parameters that will be passed into the function when it is created A list of parameters that will be passed into the function when it is created Output: A return value that will be returned by the function when called To create a module, use the New-Module cmdlet. The New-Module cmdlet allows you to create a new module and add its properties and methods. The following example creates a module named MyModule: New-Module -Name MyModule -Type Module
