Switch Statement

Mission: Decision Desk

For a day name, select one of three outcomes: weekend, weekday, or unknown.

The switch statement is an alternative to long if/else if chains when you are matching a single value against several discrete options.

Syntax

javascript
switch (expression) {
    case value1:
        // code
        break;
    case value2:
        // code
        break;
    default:
        // code when no case matched
}

When a case logs or assigns a result, use break to stop execution from falling into the next case. In a function, return also stops execution, so a case that returns does not need break.

Fall-through (sometimes intentional)

javascript
const light = "amber";
switch (light) {
    case "amber":
    case "red":
        console.log("Stop");
        break;
    default:
        console.log("Go");
}

Adjacent cases can share a result. The switch matches exact values: "Saturday" is not the same as "saturday".

Your Task

  1. Implement getDayType(day) using switch: Saturday and Sunday return "Weekend", weekdays return "Weekday", and any other name returns "Unknown". The provided Sunday probe should print Sunday: Weekend.
  2. Log Weekend pair: Weekend,Weekend from Saturday and Sunday calls.
  3. Log Weekdays: Weekday,Weekday,Weekday,Weekday,Weekday from Monday through Friday calls.
  4. Log Holiday: Unknown from an invalid name.
  5. Log Saturday: Weekend from getDayType("Saturday").
Hint 1
1 / 3
HINT 1

Each case matches the value after switch (expression).

HINT 2

Don't forget break at the end of each case to prevent fall-through.

HINT 3

Use default as the catch-all (like else).
