Map function not working in React js component

Question

I am new to react js. I am trying to use the map function on an array that is stored in another file called products.js, when I console log the data it is showing by not showing in the screen. This is my code for the component:

import React from 'react'
import products from '../products'
import {Row,Col} from 'react-bootstrap'

const HomeScreen = () => {
    console.log(products)
    return (
        <>
            <h1>Latest Products</h1>
            <Row>
                {products.map(product => {
                    <h3 key={product._id}>{product.name}</h3>
               })}
            </Row>
        </>
    )
}

export default HomeScreen

This is the product.js code:

const products = [
  {
    _id: '1',
    name: 'Airpods Wireless Bluetooth Headphones',
    image: '/images/airpods.jpg',

  },
]

export default products

And this is my App.js code:

import React from 'react'
import {Container} from 'react-bootstrap'
import Header from './components/Header'
import Footer from './components/Footer'
import HomeScreen from './screens/HomeScreen'

const App=()=> {
  return (
    <>
      <Header />
      <main>
         <Container className='py-3'>
          <HomeScreen/>
          </Container>
      </main>
      <Footer/>
    </>
  );
}

export default App;

Why is this happening? I have tried looking up some solutions but failed. Thank you for helping

Answer 1

I think the problem is that you need to add a return statement before the h3:

 <Row> {products.map(product => { return <h3 key={product._id}>{product.name}</h3> })} </Row>

Answer 2

Add a return statement in the map function.

{products.map((product) => {
    return <h3 key={product._id}>{product.name}</h3>;
  })}

Answer 3

If you want to do it this way without using 'return', there are 2 options: Option 1: Remove the curly braces

<Row>
    {products.map(product => return <h3 key={product._id}>{product.name}</h3>)}
  </Row>

Option 2: Use () instead of the curly braces (Most especially when you are gonna add more elements later)

<Row>
    {products.map(product => (
          <h3 key={product._id}>{product.name}</h3>
          <...other html elements>
    ))}
  </Row>
