Javascript Programming Tutorials, Guides & Best Practices

• The columns array specifies how data fields (e.g., username, points) map to table columns.

• language.emptyTable: Custom message displayed when no data is available.

Fetch and update filtered data dynamically without reloading the entire page.

Automatically save user inputs (e.g., in a blog editor) without refreshing the page.

• reduce: Executes a reducer function on each element of the array, resulting in a single output value.

  const numbers = [1, 2, 3, 4];
  const sum = numbers.reduce((acc, x) => acc + x, 0);
  console.log(sum); // Output: 10

axios.all([
    axios.get('https://jsonplaceholder.typicode.com/posts/1'),
    axios.get('https://jsonplaceholder.typicode.com/posts/2')
  ])
  .then(axios.spread((post1, post2) => {
    console.log('Post 1:', post1.data);
    console.log('Post 2:', post2.data);
  }))
  .catch(error => {
    console.error('Error fetching data:', error);
  });

• We use axios.all() to send multiple requests.
• The axios.spread() function is used to handle the responses separately.

• Custom Headers: Extend the hook to accept custom headers or authentication tokens in the options parameter.
• Polling: Implement a polling mechanism by setting up a setInterval within the useEffect for periodically fetching data.
• Data Transformation: Add a callback function to transform the fetched data before setting it in state.
