Hello, Glory, you wrote: (I notify at once - I not ) All of us we know sites with the infinite scrolling. This disgrace with began, is then cunning to Tumblr and further everywhere. The user page to a bottom, it from below , and so endlessly. Normally it is accompanied by absence of search in date and generally any search. This "disgrace" reminds me : something is invented well high qualification, and for certain tasks, but becomes fashionable, becomes mass and inevitably it is possible in masses to the point of irrationality. To take, apparently, dear Ozon.ru. At them the necessary information is in (about delivery, for example), and at the infinite page paging, button "End" becomes stupid ... And it all brings down the infinite goods. It is possible to open, of course, other, short p. and to look, but after all delirium. I any more do not say that on storage loads not childly. On normal sites so does not become, certainly. Sooner or later any similar page starts to brake, because elements in it becomes more than is capable to process in time an engine of the browser and any intermediate scripts on page. Attention, a question - and why anybody together with adding of elements in the end of page does not delete them from the beginning? That is, after defined the amount of "growths" of page, adding of each following element of a tape involves also removal of an element from the beginning. As a result, the page will have though also big, but nevertheless the finite size. More likely on mind removal of objects of mute objects, and them "sliding reusage", i.e. when to the place of mute objects the visible comes not. It can partially spare resources (and can not spare - it is necessary to investigate). Whether do so though somewhere, and whether there is in it a sense generally? Whether the browser will release storage which has been selected under remote elements DOM, or final clearing of storage to happen only at tab/window closing? I think, all is aggravated with that is a lot of browsers. Different engines with garbage collectors on different platforms can and work differently - nuances are possible. Well and versions are permanently updated. Today optimized, and in a year all starts to die. Better elementarily not to use the infinite p. there where really it is a lot of data. Or alternative as, for example, in some where simultaneously is both paging and the button " still", and all is convenient.
