V-show

Hello world

It is also used to display elements according to conditions. Unlike v-if, if the value of v-if is false, the element is destroyed and is not in dom. But the elements of v-show are always rendered and saved in dom, which simply toggles the dispaly property of css.

Note: v-if has higher switching overhead v-show has higher initial rendering overhead. Therefore, if you want to switch very frequently, it is better to use v-show; if the run-time conditions are unlikely to change, then v-if is better. Thank you for reading this article carefully.
