programming:
JavaScript's switch vs. C and C++'s switch

How do you use the switch statement in javascript? Is it used the same way it is in C++ (with the case statement)?

Yes, it is exactly the same, with three exceptions:

1. In C and C++, all of the case values must be the same type as the switch value.

   In JavaScript, there is no such restriction.

2. In C and C++, you cannot switch on the contents of a string.

   In JavaScript, there is no such restriction.

3. In C and C++, all case values must be unique.

   In JavaScript, there is no such restriction. The first matching case value is recognized, regardless of duplicates.

Presently, neither language will let you use variables for the case values.
