- Can jquery be used in vue?
- Yes, you can use jQuery with Vue. Vue’s progressive nature allows developers to use functionality on demand, including integration with other libraries. jQuery can be installed into a component by installing a global plugin or manually. Note that jQuery is primarily intended as a helper tool and should be used to avoid naming conflicts and code redundancy when used within the Vue ecosystem. Best practice is to only use jQuery when needed, and prioritize tools that come with Vue or third-party plugins.

- What happens when v-if and v-for are combined in vue?
