How to get the value from a Promise and handle errors?

To get a value from a Promise and handle errors in JavaScript, the .then() method is used for successful results and .catch() for errors. You can also use async/await with a try/catch block.

Example with .then() and .catch():

fetch('https://api.example.com/data')
  .then(response => response.json())
  .then(data => {
    console.log('Data:', data);
  })
  .catch(error => {
    console.error('Error:', error);
  });

Example with async/await:

async function getData() {
  try {
    const response = await fetch('https://api.example.com/data');
    const data = await response.json();
    console.log('Data:', data);
  } catch (error) {
    console.error('Error:', error);
  }
}

getData();
