Vue 3.0 TypeScript support

Vue 3.0 has a much better support for TypeScript compared to Vue 2.x. TypeScript is a statically typed superset of JavaScript that provides optional static typing and class-based object-oriented programming to the language.

Here's a basic tutorial on how to create a Vue 3.0 project with TypeScript:

Create a new Vue 3.0 project with TypeScript
Vue CLI provides an easy way to start a new Vue project with TypeScript. If you don't have Vue CLI installed, you can install it globally with npm or yarn:
```
npm install -g @vue/cli
# OR
yarn global add @vue/cli
```
Now you can create a new Vue 3.0 project with TypeScript:
```
vue create my-vue3-project
```
This will start the Vue CLI interactive project setup. For TypeScript support, select "Manually select features" > "TypeScript".
Define component with TypeScript
Here is how to define a component using TypeScript:
```
<template>
  <div>{{ greeting }} World!</div>
</template>

<script lang="ts">
import { defineComponent, ref } from 'vue'

export default defineComponent({
  name: 'HelloWorld',
  setup() {
    const greeting = ref('Hello')
    return { greeting }
  }
})
</script>
```
With TypeScript, you can see that we are using defineComponent function provided by Vue 3.0. It provides better type inference for the component options.
The setup function is part of the new Composition API in Vue 3.0. Inside setup, we declare a reactive reference greeting using ref and return it so it can be used in the template.
The lang="ts" attribute in the script tag tells Vue that this script is written in TypeScript.

Type Annotating

One of the main benefits of TypeScript is the ability to annotate types. You can use TypeScript to annotate the props in Vue components:

<script lang="ts">
import { defineComponent } from 'vue'

interface Props {
  message: string
}

export default defineComponent({
  name: 'HelloWorld',
  props: {
    message: {
      type: String,
      required: true
    }
  },
  setup(props: Props) {
    return { ...props }
  }
})
</script>

Here, we defined a Props interface for the component props and used it to annotate the props argument of the setup function.

This is a very basic introduction to using TypeScript with Vue 3.0. For more advanced usage, you might need to dive deeper into the TypeScript language itself and Vue 3.0's type definitions.
