babel-preset-stage-1 is a Babel preset that enables ECMAScript features currently in Stage 1 of the TC39 standardization process. Stage 1 proposals are considered "feature proposals" and still require significant refinement. Including this preset allows developers to experiment with these cutting-edge features in their code before they are widely adopted or finalized, understanding that the features may change or be dropped. Use with caution, as compatibility and stability are not guaranteed.
The npm package babel-preset-stage-1 saw frequent releases from October 2015 to September 2016, with a peak of 5 versions in November 2015. After that, releases became sparse, with only one release in February 2016, August 2016, September 2016, January 2017 and April 2017. No releases have occurred since April 2017, indicating the package is likely no longer actively maintained.
