React with Typescript

• In the case of TypeScript, if you want to write a function component, would it look like this?

function GuessInput({ onGuess }: { onGuess: (guess: string) => void }) { }

• Why do you have to write onGuess twice?

function GuessInput(props: { onGuess: (guess: string) => void }) { }

• Is this also acceptable?

• You can find an article on how to write React components that are less likely to receive complaints here.
