How to implement a load more button in React
import React, { useState, useEffect } from "react";
import Posts from "./Posts";
import posts from "./postsArray";
const postsPerPage = 3;
let arrayForHoldingPosts = [];
const App = () => {
const [postsToShow, setPostsToShow] = useState([]);
const [next, setNext] = useState(3);
const loopWithSlice = (start, end) => {
const slicedPosts = posts.slice(start, end);
arrayForHoldingPosts = [...arrayForHoldingPosts, ...slicedPosts];
setPostsToShow(arrayForHoldingPosts);
};
useEffect(() => {
loopWithSlice(0, postsPerPage);
}, []);
const handleShowMorePosts = () => {
loopWithSlice(next, next + postsPerPage);
setNext(next + postsPerPage);
};
return (
<div>
<Posts postsToRender={postsToShow} />
<button onClick={handleShowMorePosts}>Load more</button>
</div>
);
};
export default App;

what is the implementation of postsArray ?

I'm not showing it here but it's shown in the tutorial itself.

postsArray.js is a file that holds and exports an array of post objects.

I.e you'll have something like

const posts = [
{id:1,...}
]

export default posts

Thanks
