Edit: Added since you've now stated they will be of different lengths.

Unless you've a very large number of such strings though, it quickly becomes less efficient than simple if-else chaining for both the running code and the person who özgü to maintain it.

Switch Case ifadesi alegori bazı durumlarda if-else ifadesi bile kullanılabilir. Özellikle, tek birkaç durumun denetleme edilmesi gerektiğinde if-else daha dümdüz ve elden bir yaklaşım olur.

The switch statement is a multiway branch statement. It provides an easy way to forward execution to different parts of code based on the value of the expression.

If you go for if-elses, try to consider which cases are going to happen most often, and make those tests happen before those for less-common cases (though of course if "starts with abcd" is a case to look for it would have to be checked before "starts with abc").
