esbuild now allows specifying whether individual JavaScript features should be supported in addition to specifying the target JavaScript version for the output. This capability is now used to provide the native async/await downleveling that is required by Zone.js when using the experimental esbuild- based browser application builder. Since esbuild does not yet support downleveling async iteration or async generators, Babel is still used when either of these syntax features are detected.
