How do I use components in Vue.js?

In Vue.js, components are reusable instances with a name. You can create a component using the Vue.component method.

Can you show me an example of a simple component?

Sure! Here's a basic example:

Vue.component('my-component', {
  template: '<div>Hello from my component!</div>'
});

You can then use <my-component></my-component> in your HTML.

How do I pass data to a component?

You can pass data to a component using props. For example:

Vue.component('my-component', {
  props: ['message'],
  template: '<div>{{ message }}</div>'
});

Then use it like this: <my-component message="Hello!"></my-component>.

What if I want to use a component in another component?

You can nest components! Just register the child component in the parent component's definition and use it in the template.
