Switch statements use different syntax and rules than the more common If statements, and require some extra steps.

In this movie, we're going to be looking at a different kind of logical expression…called Switch Statements. Switch statements are similar to if statements.…In that they control the flow through our application.…But they're going to have a different syntax, some different rules to follow.…And a couple of special gotchas that we want to make sure that we watch out for.…First, let's look at the basic syntax. We're going to use the function name,…switch, followed by an argument. And that argument's going to be a value.…This is the value that we're going to be testing through each of a series of test cases.…So then in our curly braces we're going to list off those test cases.…
And each one is going to start with case, and then a test value to that we're going…to test against value to see if their equal.…And then a colon, and then a statement or series of statements that we want to execute.…Then following that will be the next case that we want to test.…So we'll test whether the values equal to test value two and if it is then we'll…
