Nodejs, why do you need to traverse the ejs engine before you can see the data in the browser? Otherwise, it is not displayed.

is to use res.render, the transmitted data is directly used as an object in ejs, not displayed, and then need to be traversed to get the data. And then it shows up in the browser.
