Fetch API in JavaScript

The browser provides the fetch() function to make HTTP requests. It returns a Promise, so you use .then() or async/await to handle the response. Always check if the response is OK before parsing JSON.

APIS
// Using fetch with promises
fetch("https://api.example.com/users")
  .then(response => response.json())
  .then(data => console.log(data))
  .catch(error => console.error(error));

// Using async/await (modern way)
async function getUsers() {
  const response = await fetch("https://api.example.com/users");
  const data = await response.json();
  console.log(data);
}
