If statements and Select-Case statements are two similar features that allow for code branching. The difference is that each If statement may compare against different variables and different ranges, while Select-Case statements may only compare against one variable at a time, and must compare against discrete values. Select-Case is therefore a specialized form of If statements, and are more efficient in terms of amount of code used and execution speed when used instead of theequivalentIf-Else statements.
