Think in PowerShell code

(1) PS has coding construct such as range, dictionary, array, function, module, for, switch,if
(2) Pipeline can do foreach, where, similarly cmdletBinding().
(3) help and get-command are similar but the latter can filter down to specific ones. 
(4) internal variable cannot get from help neither member. so get-variable and get-member would be needed.
$Subnet="192.168.0."
200..210|where{Test-connection "$Subnet$_" -count 1 -quiet}|foreach{"$subnet$_"}  #where taking in True/False by _quiet
100..120|foreach{ Test-Connection "192.168.0.$_" -count 1} help Test-Connection -wh show-command Test-Connection
100..120 | where { test-Connection "192.168.$_" -quiet } #show 100,101, 109 only success ones

Function
{
   [CmdletBinding()]
   Param (
      [parameter(Mandatory=$true, helpmessage='hel']
      $subnet,
      [int]$start
   )
   write-verbose "..." # cmdletbinding allows -Verbose common param and code inside ps1.
}

Function PipeEnabledFun()
{
  begin {}
  process { $ret=$_;}
  end {return $ret}

}

Several function made module as psm1 Import-Module.

help export, select,ExecutionPolicy.

Get-variable, $PSVersion, etc.

help get-command (better than help), get-command *counter*

Reflection:  get-service | get-member
$dict={$v="v1"; $v2="v2"}
$array="s1","s2"
if($v -eq "v") 

switch($v)
{
  41 {"test"; break;}
  default {}
}

foreach($file in get-childItem)
{
  if ($file.Name -like "test")
}

$ScriptBlock ={test-Connection}
&$scriptblock;
