PowerShell Arrays for Beginners

In this short video, I walk through the fundamentals of working with PowerShell arrays. If you’re just getting started, this is a great place to begin.

Topics Covered in the Video

• Declare an empty array

  $myArray = @()
  

• Populate the array with strings

  $myArray = "zero", "one", "two"
  

• Access elements by index

  • First element (0), last element (-1), or any position:

    $myArray[0]      # zero
    $myArray[-1]     # two
    

• Select multiple elements

  $myArray[0,2]      # zero and two
  $myArray[1..3]     # one, two, three
  

• Add elements with +=
  (recreates the array each time — fine for small lists)

  $myArray += "three"
  

• Inspect the variable type

  $myArray.GetType()
  

• List available members

  $myArray | Get-Member
  

• Check array length

  $myArray.Length
  

• Clear the array

  $myArray.Clear()
  

• Review and reuse console history

  Get-History      # alias: h
  Invoke-History 3 # alias: r 3
  

• Join array elements into a string

  $joined = $myArray -join ", "
  

• Split a string back into an array

  $newArray = $joined -split ", "
  

Arrays are one of the most common and useful data structures you’ll use in PowerShell scripting—get to know them well. Thanks for watching!
