rendering sorted array of objects using UseMemo - reactjs

Question

I'm trying to render the sorted array of objects using useMemo. Currently the last sorted array is rendering on the screen. But i want to use the select drop down where users can select different sort like title shown in code using useMemo. The users can sort by selecting title, author image.
I have used redux for sorting the array of objects.Could someone please help me with the best practice. Thanks.
I have added Post.js below the HomePage.js. Is my approach to it is wrong? Should i change the approach?
Any suggestions will be helpful.Could someone suggest me the best practies for it. Any suggestions on what am i doing wrong here?
HomePage.js
import React, { useState, useEffect, useMemo } from "react";
import Post from "../../Components/Post/Post";
import "./HomePage.css";
import axios from "axios";
const HomePage = () => {
const [posts, setPosts] = useState("");
let config = { Authorization: "................" };
const url = ".........................";
useEffect(() => {
AllPosts();
}, []);
const AllPosts = () => {
axios
.get(`${url}`, { headers: config })
.then((response) => {
const allPosts = response.data.articles;
console.log(response);
})
.catch((error) => console.error(`Error: ${error}`));
};
const newPostsByTitle = useMemo(() => {
allPosts.sort((a, b) => a.title.localeCompare(b.title)), [posts];
});
return (
<div className="home">
<div className="select">
<select
name="slct"
id="slct"
onChange={(e) => newPostsByTitle(e.target.value)}
></select>
</div>
<Post className="Posts" posts={posts} key={posts.title} />
</div>
);
};
export default HomePage;
Post.js
import React from "react";
import "./Post.css";
import { Fragment } from "react";
const Post = (props) => {
const displayPosts = (props) => {
const { posts } = props;
if (posts.length > 0) {
return posts.map((post) => {
return (
<Fragment>
<div className="Post" key={post.title}>
<img
src={post.urlToImage}
alt="covid"
width="100%"
className="img"
/>
<h5 className="title"> {post.title}</h5>
<p className="author"> {post.author}</p>
<p className="description"> {post.description}</p>
</div>
</Fragment>
);
});
}
};
return <div className="Posts">{displayPosts(props)}</div>;
};
export default Post;

There are few issues with the useMemo function.
There is no allPosts variable that will be available for that
function
There is no return inside useMemo
The dependency array syntax is wrong.
It should be something like the following.
const newPostsByTitle = useMemo(() => {
return [...posts].sort((a, b) => a.title.localeCompare(b.title));
}, [posts]);
