For example: I find Browserify helps me structure client-side code to be more reusable and easier to navigate. And, during development my browsers show the right file and line number for errors, because I use Source Maps. When I read about 6to5 being renamed to Babel the thing that interested me the most was ESTree:
Recently a number of people from Mozilla, Esprima, The jQuery Foundation, Acorn, 6to5, ESLint, and others have come together to create ESTree, a standard upon which all parser and transpiler tooling will be based on.
The ESTree Spec could be what takes the pain away from our constant quest to use the latest and greatest standards without having to wait for legacy browsers to catch up. Now we can take transpilers seriously:
We want for 6to5 to solve the transpiler story. If the community could rally around a tool that provides a solid foundation for dealing with a lot of shared issues then we’ll all be much better off.
