Flow

Code>	Explanation
If (1 -eq 1) { }	Do something if 1 is equal to 1
Do { 'hi' } While ($false)	Loop while a condition is true (always executes at least once)
While ($false) { 'hi' }	While loops are not guaranteed to run at least once
While ($true) { }	Do something indefinitely
While ($true) { if (1 -eq 1) { break } }	Break out of an infinite while loop conditionally
For ($i = 0; $i -le 10; $i++) { Write-Host $i }	Iterate using a for..loop
ForEach ($item in (Get-Process)) { }	Iterate over items in an array
Switch ('test') { 'test' { 'matched'; break } }	Use the switch statement to perform actions based on conditions. Returns string 'matched'
Switch -Regex (@('Trevor', 'Daniel', 'Bobby')) { 'o' { $PSItem; break } }	Use the switch statement with regular expressions to match inputs NOTE: $PSItem or $_ refers to the "current" item being matched in the array
Switch -Regex (@('Trevor', 'Daniel', 'Bobby')) { 'e' { $PSItem } 'r' { $PSItem } }	Switch statement omitting the break statement. Inputs can be matched multiple times, in this scenario.
