Vue Tip: When to Use v-if

Vue Tip: When to Use v-if Image

During toggles, v-if entirely creates and destroys the element, including event listeners and child components:

2  <MyComponent v-if="showComponent" />

v-show creates the element and only toggles its visibility using CSS.

2  <MyComponent v-show="showComponent" />


Generally speaking, v-if has higher toggle costs while v-show has higher initial render costs. So prefer v-show if you need to toggle something very often and v-if if the condition is unlikely to change at runtime.
