![]() ![]() ![]() ![]() Remember that case values are tested with strict equality ( =). There are four steps: Identify the problem you need to solve Break the problem down into smaller problems Solve each small problem Assemble your solutions into the final solution. If break is omitted, the program continues execution at the next statement in the switch statement. You can solve any problem you encounter with JavaScript. The optional break statement associated with each case label ensures that the program breaks out of switch once the matched statement is executed and continues execution at the statement following switch. The curriculum has previously taught tens of thousands to write. By convention, the default clause is the last clause, but it does not need to be so. This course features freeCodeCamps basic JavaScript curriculum recorded as Scrimba screencasts. If no default clause is found, the program continues execution at the statement following the end of switch. 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. (If multiple cases match the provided value, the first case that matches is selected, even if the cases are not equal to each other.) It then looks for the first case clause whose expression evaluates to the same value as the result of the input expression (using the strict comparison, ( =) and transfers control to that clause, executing the associated statements. Selecting from Many Options with Switch StatementsĪ switch statement first evaluates its expression. ![]()
