Button component is getting rendered twice every time - reactjs

Question

I tried to increment the count whenever i click the button. When click the button it is getting rendered twice. But it should be render only once.
Here is my code
https://codesandbox.io/s/async-pine-3z2ty3?file=/src/App.js
import { useCallback, useMemo, useState } from "react";
import Button from "./Button";
export default function App() {
const [count, setCount] = useState(0);
const [count1, setCount1] = useState(0);
const handleClick = useCallback(() => {
setCount(count + 1);
}, [count]);
const MyButton1 = useMemo(
() => <Button handleClick={handleClick} title="Increment Count" />,
[handleClick]
);
const MyButton2 = useMemo(
() => (
<Button handleClick={() => setCount1(count1 + 1)} title="Click here" />
),
[count1]
);
return (
<div className="App">
<div>count : {count}</div>
{MyButton1}
<div>count1 : {count1}</div>
{MyButton2}
</div>
);
}
import React from "react";
const Button = React.memo(({ handleClick, title }) => {
console.log(title);
return <button onClick={handleClick}>{title}</button>;
});
export default Button;

Problem
Your handleClick function changes count
If count changes new handleClick is created
If handleClick changes you create new <Button>
Solution
Remove redundant useMemos
Pass a function to setCount
Remove dependency from useCallback
export default function App() {
const [count, setCount] = useState(0);
const [count1, setCount1] = useState(0);
const handleClick = useCallback(() => {
setCount((count) => count + 1);
}, []);
return (
<div className="App">
<div>count : {count}</div>
<Button handleClick={handleClick} title="Increment Count" />
</div>
);
}
Now your component will be rendered once at the beginning and never again
If you want to have two buttons, you have to have two callbacks
export default function App() {
const [count, setCount] = useState(0);
const [count1, setCount1] = useState(0);
const handleClick = useCallback(() => {
setCount((count) => count + 1);
}, []);
const handleClick1 = useCallback(() => {
setCount1((count) => count + 1);
}, []);
return (
<div className="App">
<div>count : {count}</div>
<Button handleClick={handleClick} title="Increment Count" />
<div>count : {count}</div>
<Button handleClick={handleClick1} title="Click here" />
</div>
);
}
