FPS refresh rate per second

(1) FPS refers to the frame number of the screen

FPS refers to the number of frames per second frame, popular refers to the game and animation or video, the number of frames per second, the more the display of the action will be smoother, this value is higher the better, because the higher the number of frames per second, the more frames, the more the picture is refreshed per second, This is related to the graphics card and CPU (but mostly the graphics card)

(2) The cost of Reflow is much higher than the cost of Repaint. The Reflow of a node is likely to lead to sub-nodes, even the Reflow of the parent and sibling nodes. There may be nothing on some high-performance computers, but if Reflow occurs on a mobile phone, the process is slow to load and drain.
