One of the things that makes Svelte so powerful is its component-based architecture. Components are reusable pieces of code that can be used to build complex user interfaces. In this blog post, we will discuss Svelte components and props. We will learn how to create components, how to pass props to components, and how to use props to control the behavior of components. ## What are Svelte Components? Svelte components are reusable pieces of code that can be used to build complex user interfaces. Components are defined using the `Svelte` tag. For example, the following code defines a component called `Button`: Copied! 🐾 " aria-label="Copy code" title="Copy code to clipboard"> ``` Click Me! ``` The `Svelte` tag takes two arguments: the name of the component and the component's code. In this case, the component's name is `Button` and the component's code is a simple button. ## What are Props? Props are variables that are passed to components. Props can be used to control the behavior of components. For example, the following code passes a `text` prop to the `Button` component: Copied! 🐾 " aria-label="Copy code" title="Copy code to clipboard"> ``` {text} ``` The `text` prop is used to set the text that is displayed on the button. ## How to Use Props Props can be used to control the behavior of components in a variety of ways. For example, you can use props to: - Set the value of a component's properties - Call a component's methods - Prevent a component from being rendered ## Conclusion Svelte components and props are a powerful way to build complex user interfaces. Components can be reused to save time and code, and props can be used to control the behavior of components. If you are new to Svelte, I encourage you to learn more about components and props. They are a key part of the Svelte framework and can help you build better web applications. ✏️ Visual Architecture Diagram ## how this course connects together.
