Default Values with Interface in Arrow Function (TypeScript, React)

This question is specific to arrow functions. Is it possible to include the default values alongside an interface in the function parameters, and without resorting to Object.assign()?

interface Props {  someBoolean?: boolean;  anotherBoolean?: boolean;  children: any;}const DefaultValues = {  someBoolean: false,  anotherBoolean: false,}export const StackOverflow: React.FC<Props> = (_props: Props) => {  const props = Object.assign({}, _props, DefaultValues);  return <React.Fragment>{props.children}</React.Fragment>;};
