Note that getting a small size for the react-icons benchmark relies on an unsafe transformation where the side effects of assignments to the displayName property must be ignored. This is unsafe because the displayName property may have a setter that runs other side effects. If those assignments are commented out, esbuild generates a 9.5kb bundle.

How to use it
