Refactoring JavaScript to ES2023+ involves updating vanilla JS projects with optional chaining, nullish coalescing, top-level await, and modern array methods. This process improves code reliability and readability across both frontend and Node.js backends while ensuring strict adherence to ESM modules.

Handling async flows in Node.js backends is best achieved using async/await patterns and Promise handling. This approach ensures clean, readable code execution and allows for comprehensive error handling through try/catch blocks, significantly improving backend reliability.

Yes, you can use ESM modules and dynamic imports in vanilla JavaScript projects. Implementing ESM imports and exports alongside dynamic imports ensures proper module system usage, which is fully supported across modern frontend and Node.js environments for better code organization.

Optional chaining and nullish coalescing directly improve JavaScript code quality by safely handling undefined or null values. These ES2023+ language features prevent runtime errors and reduce verbose conditional checks, resulting in much cleaner and more reliable code.

Using modern ES2023+ array methods and private fields enhances JavaScript projects by providing built-in data transformation capabilities and strict encapsulation. These features contribute to better performance considerations and comprehensive code quality reviews.

Top-level await in frontend JavaScript is limited to ES modules and cannot be used in standard scripts. While it simplifies async initialization, developers must ensure proper error handling with try/catch to manage uncaught promise rejections effectively.
