Honestly, why invest time re-writing an ES2015 transpiler? Hasn't this area already been sufficiently covered by existing tools (especially since the author explicitly "limits [Buble} to ES2015")?

Because it's many times faster (~4x faster with small files, ~20x faster with large files), very easy to set up, and tiny (which has a significant impact on CI – it's very quick to install). It also generates leaner code, and doesn't rewrite the parts that don't need to be transpiled, so your style/formatting is preserved. We need to update the docs – it actually supports ES2016 (only one new language feature – the exponentiation operator) and may support JSX in future.

  How does it compare to the Typescript transpiler? Do you have benchmarks somewhere?

    Not yet, though I agree that would be worthwhile

      If your selling point is speed, I agree that a benchmark would be worthwhile..

        Compared to Babel, which he clearly had a benchmark for. No need to get toxic.
