Debugging in PowerShell is similar to that in other programming languages. Script debugging is available in the console host as well as in the PowerShell ISE; ISE has both GUI and cmdlet-based debugging, whereas console has only cmdlets to debug your scripts.
The debugging feature in the PowerShell ISE is available under the Debug tab, which is self-explanatory. Let's take a look at the breakpoints and debug cmdlets:
(Get-Command -Name *Debug*).Where({$_.Source -ne 'Azure' -and $_.CommandType -eq 'cmdlet'}) Get-Command -Name *BreakPoint
Note that in the first snippet, I used the where method to ignore Azure and to get only the core cmdlets; the output is illustrated in the following image:
