use named export rather than default export

[xiaoxiangmoe]

In TypeScript Documentation it write:

import * as React from "react";

but in cra, it use:

create-react-app/packages/react-scripts/template-typescript/src/index.tsx

Lines 1 to 2 in fbb3b03

	import React from 'react';
	import ReactDOM from 'react-dom';

Should we use named export rather than default export?

Named export seems to be a more accurate way of expressing the export of react.

Neither of the examples provided are named exports. A named export would be:

import { Component } from "react"

We enable esModuleInterop in TypeScript for compatibility with Babel/commonjs modules which enables synthetic default import support. You can read more at https://itnext.io/great-import-schism-typescript-confusion-around-imports-explained-d512fc6769c2
