Typescript import best practices?

Is there a difference in the compiled package between import { useEffect } from "react" vs
import * from "react"
React.useEffect(() =>{})
import * from "react"
React.useEffect(() =>{})
? I remember someone showing how import Box from "@mui/material/Box"; was significantly different than import Box from "@mui/material"; and wasn't sure if this was similar.

I just ran a quick test with create-react-app (react 18) and confirmed that the difference in compiled package between useEffect vs React.useEffect has zero impact on the resulting package.

Thanks. I haven't used one of those before, I'll dig into it. Interestingly the difference between import Box from '@mui/material/Box and import {Box} from '@mui/material is also 0 with latest versions.

Named imports are better than default imports because if it can be tree shaken it will be, default can never be. It took me ages to figure out how to make a treeshakable lib, the only tool at the time that seemed to work was roll up, webpack could treeshake a build but at the time couldn't make something that was treeshakable. There is a subtle difference between tree shaking and a bundler that omits unused code.
