+You can specify a default initial value for a prop. It will be used if the component's consumer doesn't specify the prop on the component (or if its initial value is `undefined`). Note that whenever a prop is removed by the consumer, its value is set to `undefined` rather than the initial value.
 In development mode (see the [compiler options](docs#svelte_compile)), a warning will be printed if no initial value is provided and the consumer does not specify a value. To squelch this warning, ensure that an initial value is specified, even if it is `undefined`.
