Why This Works

By switching to the latest Node.js image:

You ensure you have the latest features and security updates.

Compatibility issues with new syntax introduced in ECMAScript versions will be mitigated.

You will likely see improved performance and fewer errors during the build process.

Conclusion

Building a React application with CircleCI should be a smooth process, but sometimes configuration issues arise that can lead to frustrating errors. By ensuring that you are using the latest Node.js version, you can avoid common pitfalls related to package compatibility.

Next time you face an error like the fs-extra module's SyntaxError, remember to check your Node.js version first!
