I need a modern JavaScript REPL tool that works flawlessly with new syntax in Visual Studio Code. Current alternatives are outdated or limited; are there any reliable and free options available?
I have switched to using the integrated Node.js REPL in Visual Studio Code along with the latest Node version and it works quite well with modern syntax. I simply run Node directly from the integrated terminal, and it supports ES modules, async/await, and the latest ES features without any additional fuss. For some scenarios, I also use Babel to precompile if needed, but in most cases the native environment suffices. It provides an up-to-date, reliable, and free solution that blends seamlessly with the VSCode ecosystem, ensuring I can test code on the fly efficiently.
In my experience, Quokka.js has proven to be an excellent replacement for traditional REPL tools. It integrates exceptionally well with Visual Studio Code, providing real-time feedback as your code is executed. The tool supports modern ES syntax, including modules and async functions, so it aligns with current JavaScript standards. I found its setup straightforward and effective for interactive coding sessions. The live feedback feature not only helps in quickly testing snippets but also in identifying issues on the fly, which has significantly streamlined my development process.
