If break is omitted, the program continues execution at the next statement in the switch statement. If multiple cases match the provided value, the first case that matches is selected, even if the cases are not equal to each other. If no matching case clause is found, the program looks for the optional default clause, and if found, transfers control to that clause, executing the associated statements. The source for this interactive example is stored in a GitHub repository. If the expression matches the specified valueN, the statements inside the case clause are executed until either the end of the switch statement or a break.

Methods for multi-criteria case Source for this technique is here: Multi-case - single operation This method takes advantage of the fact that if there is no break below a case statement it will continue to execute the next case statement regardless if the case meets the criteria. In JavaScript, you can even mix in definitions of strings into these case statements as well. This shows you that it will traverse in the order that you put the case statements, and it does not have to be numerically sequential. .
