So in the example below, we display only 2 products from the array, and once the user clicks on the button the method load more is triggered and the products to show are incremented by 2.
import React,{useState} from 'react';
export default function ProductList() {
const products = [
{
id: 1,

];
const [productToShow, setProductToShow] = useState(2);
const loadMoreProducts = () => {
if(productToShow >= products.length){
return;
}else{
setProductToShow(prevProductToShow => prevProductToShow + 2);
}
}
return (
<div className="row my-4">
{
products.slice(0, productToShow).map(product => (
<div className="col-md-4" key={product.id}>
<div className="card mb-2" style={{width: '18rem'}}>
<img src={product.image} className="card-img-top" alt={product.name} />
<div className="card-body">
<h5 className="card-title">{product.name}</h5>
<p className="card-text">Some quick example text to build on the card title and make up the bulk of the card's content.</p>
<button className="btn btn-primary">
<i className="bi bi-cart-check-fill"></i> Add to cart
</button>
</div>

))
}
{
productToShow < products.length && <div className="my-3">
<button className="btn btn-danger" onClick={() => loadMoreProducts()}>
