Я не могу печатать простые даты JavaScript внутри React.
import React, { Component } from 'react';
import './ActivityWarningText.css';
class ActivityWarningText extends Component {
render() {
const str = new Date();
return(
<div>
<h1>All activity is recorded. {str}</h1>
</div>
)
}
}
export default ActivityWarningText;
Я получаю эту ошибку:
Objects are not valid as a React child (found: Wed Apr 25 2018 18:09:03 GMT+0400 (Arabian Standard Time)). If you meant to render a collection of children, use an array instead.
in h1 (at index.js:17)
in div (at index.js:16)

in component (created by Route)

Это работает, однако, str.getFullYear()
