VistasIs there a difference to importing specific functions/variables vs importing it entirely?
When importing functions in for example, ReactJS, I normally import only specific functions.
import { useEffect, useState, /* ETC... */ } from 'react';
But is there a difference to just importing the whole module?
import React from 'react';
Except for the fact that you'll need to do React.useState() instead of useState(), is there a difference in performance? Does it load faster etc. I know it probably reads the entire file in both cases but is anything else affected?

It's a very good question. I have already installed the extension Import Cost from VSCode which let you know the import size cost of each library and the way you import that.
This library has a post explaining it in detail. Medium Import Cost Post
I try to test it and the result is different depending on the way you import everything or just the method.
