Lines of code is a useless metric by itself. You need proper metrics before saying something like “9 lines becomining[sic] 75 doesn’t scale well.”
- Is this a one-time hit?
- What extra complexity has it added?
Are the real questions you should ask. If you ran a one liner through webpack, you’d end up with a lot more lines than just one. Does that mean webpack doesn’t scale well? Similarly if you ran a simple printf(“Hello World\n”); through gcc, you’d end up with a lot more assembly than if you would have written it yourself. You might be right that the polyfilled solution for async/await might not be worth it at this time, but you sure haven’t given any remotely valid reason for it.
