Run Java script code Synchronously inside a function with promises

javascript 6 years, 6 months ago

async function showAvatar() { // read our JSON let response = await fetch('/article/promise-chaining/user.json'); let user = await response.json(); // read github user let githubResponse = await fetch(`https://api.github.com/users/${user.name}`); let githubUser = await githubResponse.json(); // show the avatar let img = document.createElement('img'); img.src = githubUser.avatar_url; img.className = "promise-avatar-example"; document.body.append(img); // wait 3 seconds await new Promise((resolve, reject) => setTimeout(resolve, 3000)); img.remove(); return githubUser; } showAvatar();

JavaScript follows Asynchronous way of running code when this comes to promises. If we give Async-Await then it works synchronously. It's just a suggestion that if you need the thing strongly then go for it. otherwise just process the request much before.
