In the previous article on changing the flow of PowerShell code, I wrote on looping in PowerShell, providing scenarios for when to use what. In the fourth article in the Practical PowerShell series, I talk about code branching.
Topics discussed are the If-Then-Else, Switch (albeit briefly as its use cases are extensive), and stop cmdlets such as break-continue-return-exit. On the side, I will also touch briefly on unary operators.
