The most fascinating topic to learn about today is highly beneficial for every JavaScript developer.π π₯οΈ.
async/await :
- It is primarily used for managing asynchronous code.
async and await are syntax enhancements in JavaScript that make it easier to work with Promises. They allow you to write asynchronous code that looks and behaves like synchronous code.
async: You can add the async keyword before a function to make it an asynchronous function. An async function always returns a Promise.
awaitβ: You use the await keyword inside an async function to pause the execution of the function until the Promise is settled.
Error Handling π΄:
Handling errors in async/await is done using try/catch blocks, just like with synchronous code.
async function fetchData() {
try {
let response = await fetch("URL");
if (!response.ok) throw new Error("Network response was not ok");
let data = await response.json();
console.log(data);
} catch (error) {
// the error will be caught in the catch() block
console.error("Error fetching data:", error);
}
}
fetchData();
