21. ERR-03 Avoid using flags to handle errors
Try to avoid setting flags:
““
Try {
$continue = $true
Do-Something -ErrorAction Stop
} Catch {
$continue = $false
}
if ($continue) {
Do-This
Set-That
Get-Those
}
Instead, put the entire "transaction" into the Try block:
Try {
Do-Something -ErrorAction Stop
Do-This
Set-That
Get-Those
} Catch {
Handle-Error
}
““
It’s a lot easier to follow the logic.
