You can dynamically render Svelte components without using if-statements by creating separate child components for each desired format and then choosing which one to render based on a prop value. This approach allows you to keep your styling separate, cut down on messiness, and easily add more post formats in the future. By using Svelte's built-in dynamic rendering feature, `svelte:component`, you can pass the correct child component as a prop to the parent component, allowing for flexible and reusable code.
