Why do scrolling load or click to load more of this function?

recently, one of the requirements of the vue project is to click to load more functions, and then Baidu sees that everyone is saving the data into an array, and then click to load (that is, to get the value of the array).
there is a question here. Why do click loading speed up the loading speed of the page, so is the return of js data slow or the page rendering slow?
according to everyone"s answer from Baidu, it feels that the data rendering page is slow.
