There don't appear to be any immediate technical differences between the two codes you provided. Both use Vue.js for front-end development and TypeScript with ES modules for dynamic imports of components.

As a general guideline, when it comes to optimizing existing code:

• Check if any unnecessary lines or blocks that can simplify complexity have been removed.
• Ensure your Vuex store is correctly implemented to manage state efficiently (e.g., using getters, actions, etc.)
• Make sure all dependencies in a component are properly managed (i.e., scopedSlots)
• Consider refactoring the code into smaller, more readable chunks

Since these questions ask "optimization" but not specific details ("what could I optimize") and both were submitted before my instruction cutoff of September 2021, there's less concrete guidance on whether they're actually outdated from an optimality perspective.

However, given that this was asked about current-day Vue.js applications with JavaScript syntax, here’s where I would go next:

The first code block uses style attribute which should be kept minimalistic because browsers implement styles via css rules without requiring inline tags.

Secondly, keep vue.config.ts files out of your source control, since they contain sensitive information about the configuration of your application.

Lastly, consider adding unit tests to ensure the functionalities work as expected under a variety of conditions.

Remember though, optimizations need context-specific understanding; always check modern best practices regarding those changes.
