will removing unused import reduce file size

[artofspeed]

In dev mode, browser gives warning when react have unused import. Question is, if i remove them, will the built js file (created by npm run build) have less size?

Thanks!

You should just try it :) It will be very easy to tell.

Yep, give it a try :-).

Is it possible for build system to automatically remove them?

No, imports may have side effects.
