This code is editable. Java Tutorials.

The expression is evaluated The first case, x, will be tested against the expression. If it matches, the code will execute, and the break keyword will end the switch block.

If it does not match, x will be skipped and the y case will be tested against the expression. If y matches the expression, the code will execute and exit out of the switch block. If none of the cases match, the default code block will run. Let's make a working example of a switch statement following the syntax above. In this code block, we will find the current day of the week with the new Date method, and getDay to print a number corresponding to the current day.

We'll start by setting up our variable.

Learning JavaScript Design Patterns

The program will run in order from top to bottom looking for a match, and once one is found, the break command will halt the switch block from continuing to evaluate statements. You got this!

Depending on what day of the week you are testing the code, your output will be different. We have included a default block at the end to run in case of an error, which in this case should not happen as there are only 7 days of the week.

We also could have, for example, only printed results for Monday to Friday, and the default block could have had the same message for the weekend. If we had omitted the break keyword in each statement, none of the other case statements would have evaluated to true, but the program would have continued to check until it reached the end.

In order to make our programs faster and more efficient, we include the break. Switch Ranges There might be an occasion in which you will need to evaluate a range of values in a switch block, as opposed to a single value as in our example above.

We can do this by setting our expression to true and doing an operation within each case statement. To make this easier to understand, we will use a familiar example. In the conditional statements tutorial, we made a simple grading app which would take a number score and convert it to a letter grade, with the following requirements.

Since we're checking a range, we will perform the operation in each case to check if each expression is evaluating to true then break out of the statement once the requirements for true have been satisfied.This gives us a clean solution for shielding logic doing the heavy lifting whilst only exposing an interface we wish other parts of our application to use.

As a result, the scope object will not be garbage-collected until there are no more references to the function object that makeAdder returned. Say that we're using such an assumption to log or output errors regarding some application process.

To defend the idea of JavaScript against competing proposals, the company needed a prototype. The try Switch The switch statement evaluates an expression and executes code as a result of a matching case.

For the output, you have the following options: They also help us identify what layers containing direct relationships which could instead be replaced with sets of subjects and observers. Variables defined with var move to the top when the code is executed.
