How do I set up a Vue 3 project using the setup script?

To set up a Vue 3 project using the setup script, you can use the Vue CLI. First, install it if you haven't already.

What commands do I need to run?

Run npm install -g @vue/cli to install the Vue CLI, then create a new project with vue create my-project.

How do I use the setup script in my components?

In your component, you can define the setup function like this: setup() { /* your logic */ }. This is where you can use reactive properties.

Can you give me an example of using reactive properties?

Sure! Inside the setup function, you can import ref from Vue and create a reactive variable like this: const count = ref(0);.
