Parse Error: Adjacent JSX elements must be wrapped in an enclosing tag

Parse Error: Adjacent JSX elements must be wrapped in an enclosing tag!

React doesn’t like siblings. More specifically, it doesn’t allow siblings in a return function while rendering.

We should put your component between enclosing tags,

Wrong ways!

import React from 'react';

class MyComponents extends React.Component {
    render() {
        return (
            <MyComponent1/>
            <MyComponent2/>
            <MyComponent3/>
        );
    }
}
export default MyComponents;

Correct Ways!

import React from 'react';

class MyComponents extends React.Component {
    render() {
        return (
            <>
                <MyComponent1/>
                <MyComponent2/>
                <MyComponent3/>
            </>
        );
    }
}
export default MyComponents;

As an example to resolve this issue using <> </>,

import React from 'react';
import { Helmet } from "react-helmet";

class MyComponents extends React.Component {
    render() {
        return (
            <>
                <h2>Section 1 - for React Helmet</h2>
                <Helmet>
                    <meta charSet="utf-8" />
                    <title>React Helper functions</title>
                    <meta property="og:type" content="website - tech blog" />
                    <meta property="og:site_name" content="code sample" />
                </Helmet>

                <h2>Section 2 - React Helper functions</h2>
                <div>
                    <p>React Helper functions</p>
                </div>

                <h2>Section 3 - Other</h2>
                <div>
                    <p>Other</p>
                </div>
            </>
        );
    }
}
export default MyComponents;
