# exitApp

[Built-ins](README.md)

Canonical ID: `app.exit`. Nederlands: `sluitApp`.

Immediately finishes the entire program successfully, including remaining functions, loops, event scripts, and pending timers. It takes no status-code argument. In the [IDE](../concepts/ide.md) or browser it ends the program session and preserves the preview for inspection. A native application requests normal host shutdown; it does not wait indefinitely on its last frame. Use return when only the current function should finish.

## Signature

```text
exitApp()
```

## Arguments

This call takes no arguments. Always write the parentheses.

## Return value

Does not return.

## Example

```pliro
# language: en
function finish():
    say "Pliro"
    exitApp()

finish()
say "unreachable"
```

Only `Pliro` is printed; the call does not return.

## Notes and common mistakes

Use the function name for your source language. Its [canonical ID](../concepts/canonical-identity.md) is a shared documentation label; you do not type that ID as a call. Giving your own variable or function the same name can hide the built-in. Supply the documented [arguments](../concepts/parameters-and-arguments.md) and value types. Pliro reports mismatches when checking can detect them, or when the call runs.
