反应时收到 no-undef 错误怎么办？

Question

I get this error when trying to run the page...

import React from "react";
import reactDom from "react-dom";

const element = <h1>Hello World</h1>;
ReactDOM.render(element, document.getElementById('root'));

Answer 1

I think this is a syntax error, reactDom is not the same as ReactDom can you try:

import React from "react";
import ReactDom from "react-dom";

const element = <h1>Hello World</h1>;
ReactDom.render(element, document.getElementById("root"));
