This code is a React component that allows users to generate a PDF file of specific content within the component using the react-to-pdf library. Here's a breakdown of how it works:

Imports
useRef from React: This is a hook that allows you to directly create a reference to a DOM element in your functional component.
generatePDF from react-to-pdf: This is a function provided by the react-to-pdf library which converts a referenced DOM element to a PDF.
Component Definition
Component is a functional React component.
useRef Hook
const targetRef = useRef();: Creates a reference that can be attached to a DOM element. targetRef will later be used to refer to the content that needs to be included in the PDF.
JSX
The component returns a JSX structure:
A button element with an onClick event handler. When this button is clicked, it triggers the generatePDF function.
The generatePDF function is called with two arguments: targetRef and an options object {filename: 'page.pdf'}. The targetRef points to the content to be included in the PDF, and the filename specifies the name of the generated PDF file.
A div element with ref={targetRef}. This is the content that will be converted to a PDF. The content of this div will be included in the generated PDF.
How It Works
Reference Creation: The useRef hook creates a reference (targetRef) which is attached to the div element containing the content to be included in the PDF.
Button Click: When the "Download PDF" button is clicked, the generatePDF function is called.
PDF Generation: The generatePDF function uses the targetRef to locate the div element and generate a PDF with its content. The PDF file will be named page.pdf.
