Certainly, let's dive into async/await in TypeScript!

Async/Await in TypeScript

async/await is a syntactic sugar for working with promises in JavaScript and TypeScript. It provides a cleaner and more readable way to handle asynchronous operations compared to traditional Promise chains.

How it Works

async Keyword:

Declares a function as asynchronous.
This means the function will implicitly return a Promise.
await Keyword:

Used within an async function.
Pauses the execution of the function until the Promise resolves.
The value of the resolved Promise is then assigned to the variable.
Example:

TypeScript

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

fetchData()
  .then(data => {
    console.log(data);
  })
  .catch(error => {
    console.error('Error:', error);
  });
