Lebab

Lebab provides specific, well-documented transforms for common ES5 to ES6 conversions, such as arrow functions and classes, with clear rules on applicability and limitations.

The tool allows applying one transform at a time, enabling gradual codebase upgrades and reducing risk, as emphasized in the README's recommendation to inspect diffs carefully.

It clearly distinguishes between safe and unsafe transforms, listing known bugs and limitations for each, helping developers assess and mitigate risks during the upgrade process.

With plugins for popular editors like VSCode, Atom, and Sublime, Lebab integrates seamlessly into development workflows, facilitating on-the-fly code transformations.
