Why should you care?

When a variable can be "pending", "shipped", or "delivered", switch keeps the code readable.

See it live — copy this example

Paste into an HTML file or the browser console (F12). Use Run below when the live editor is available.

let status = "shipped";

switch (status) {
  case "pending":
    console.log("Order received");
    break;
  case "shipped":
    console.log("On the way");
    break;
  default:
    console.log("Unknown status");
}

Run Example »

Edit the code below and click Run to see the result in Toolliyo’s live editor.

What happened?

• switch compares status to each case.
• break stops fall-through to the next case.
• default runs when nothing matches.

Practice next

1. Change status to "pending" and "delivered".
2. Remove break after "shipped" and observe fall-through.
3. Add a default case for unknown values.
4. Use switch(true) with comparison cases for numeric ranges.
5. Group multiple case labels that share one console.log block.

Remember

switch (value) { case x: ... break; } Use default for no match Always break unless fall-through is intentional

ScriptVerse order tracker

Order status from the API maps to user-facing messages via switch on status codes.

Outcome: Switch keeps shipment state handling readable as the business adds new statuses.
