Level 2

I tried loading jQuery in the file, but I encountered difficulties. Many tutorials mention that after loading jQuery, you can directly use it. However, most of them assume that the reader already has extensive WordPress experience, which makes it very frustrating for me.functions.php

Here’s what I need to know:

1. File paths and code placement

Where, specifically, do I need to add the code? Which files should I modify?

2. Loading jQuery for a single page

How can I load my jQuery code only for a specific WordPress page?
