 * This is a TypeScript React function that converts HTML to React Native components.
 * @property {string} html - A string containing HTML code that needs to be converted to React Native
 * components.
type Props = {

/* This is a function that takes in an object with a string property called `html` and returns an array
of React Native components (`JSX.Element[]`). The function uses the `cheerio` library to parse the
HTML string and then iterates through each HTML element using the `each` method. For each element,
the function checks the element's tag name and creates a corresponding React Native component. For
example, if the tag name is `p`, the function creates a `Text` component with the element's text
content. If the tag name is `img`, the function creates an `Image` component with the element's
`src`, `width`, and `height` attributes. The function recursively calls itself for any `div`
elements to handle nested HTML. Finally, the function returns an array of all the created React
Native components. */
