State Updates Not Reflecting

[Sachin2815]

Hi,

I'm using setState to update my component's state, but the changes aren't appearing in the UI. Here's a simplified code snippet:

import React, { useState } from 'react';

const MyComponent = () => {
  const [count, setCount] = useState(0);

  const handleClick = () => setCount(count + 1);

  return (
    <div>
      <p>Count: {count}</p>
      <button onClick={handleClick}>Increment</button>
    </div>
  );
};

export default MyComponent;

Any ideas on why the state update might not be reflecting?

Thanks!

Hi,

It looks like you might be facing a common issue where the state update isn’t reflecting due to how you’re updating the state. When using functional updates with setState, you should pass a function to ensure you’re working with the most recent state. Try this:

import React, { useState } from 'react';

const MyComponent = () => {
  const [count, setCount] = useState(0);

  const handleClick = () => setCount(prevCount => prevCount + 1);

  return (
    <div>
      <p>Count: {count}</p>
      <button onClick={handleClick}>Increment</button>
    </div>
  );
};

export default MyComponent;
