React

A component is a piece of reusable code that represents a part of a user interface. It used to render, manage, and update UI elements.

Your own react components, like Board and Square must start with a capital letter.

export default function Square() {  // define main exportable function
  return <button className="square">X</button>; // return JSX element to function caller
}

To “remember” things, components use ==state, useState==.
