Full Example

<goscript client>
    import "stew/io"

    onDelete := func() {
        if Confirm("Are you sure you want to delete?") {
            Console.Log("Action confirmed")
            // Deletion logic...
        } else {
            Console.Warn("Action cancelled")
        }
    }
</goscript>

⚡ Performance: This package is extremely lightweight as it directly uses native functions from the Go Wasm runtime.
