This section points out the offers we can take advantage of inside our application which undertake the compound component pattern of developing components in React. This instance is usually a Menu component from your @arrive at UI package deal.

In TypeScript, we have defined two interfaces representing our prop types and share the identical PieceProps concerning the two the Pawn and King component.

You can find that ” > ” character inside the return in the purpose inside that is certainly perplexing (I even imagined it absolutely was a Particular new syntax of react…you never ever know!
