It is now very popular to develop front-end and back-end separation. When searching on the Internet, some of them use nodejs to request other back-end apis and then render the page, that is, node is used as the middle layer. Another method is a pure html page, and all interfaces use ajax to asynchronously request data. Isn't the latter more convenient? Why use node as the middle layer?
