B.5. switch Fall Through

The switch statement was modeled after the FORTRAN IV computed go to statement. Each case falls through into the next case unless you explicitly disrupt the flow.

Someone wrote to me once suggesting that JSLint should give a warning when a case falls through into another case. He pointed out that this is a very common source of errors, and it is a difficult error to see in the code. I answered that that was all true, but that the benefit of compactness obtained by falling through more than compensated for the chance of error.
