Describe the bug / provide steps to reproduce it
Hello Acode Developer Team,
First of all, thank you for providing a powerful and lightweight code editor for Android. Acode has been very helpful for many developers who rely on mobile devices for learning, quick edits, and on-the-go development.
I would like to request an improvement regarding JavaScript syntax support, specifically for ECMAScript 2021 Numeric Separators (example: 3_500_000). Currently, Acode’s JavaScript parser reports this syntax as invalid, even though it is fully supported in ES2021 and modern JavaScript environments such as Node.js, Deno, Bun, and all major browsers.
This limitation affects code readability, especially when working with large numbers. Numeric separators are a standard feature and are widely used in modern JavaScript projects, teaching materials, and real-world codebases.
Why this update is important:
- Improves readability for large numbers
- Matches modern JavaScript standards
- Prevents false syntax errors
- Supports learners who study from ES2021+ documentation
- Ensures compatibility with current development practices
Suggested solution:
- Update the Ace Editor JavaScript mode to support ES2021
- Or apply a patch to the internal JS parser to accept numeric separators
- Or add a configuration option (e.g., "ecmaVersion": 2021")
I believe this enhancement will greatly improve the development experience on Acode and align it with modern JavaScript specifications.
Thank you for your time and consideration. I truly appreciate your continued work on improving the editor.
Best regards,
Acode user and JavaScript learner
