The keyword async before a function makes the function return a promise: Example. async function myFunction () { return "Hello"; } Is the same as: function myFunction () { return Promise.resolve("Hello"); } Here is how to use the Promise:
Une fonction asynchrone est une fonction précédée par le mot-clé async, et qui peut contenir le mot-clé await. async et await permettent un comportement asynchrone, basé sur une promesse (Promise), écrite de façon simple, et évitant de configurer explicitement les chaînes de promesse.

async function - JavaScript | MDN - MDN Web DocsThe async function declaration creates a binding of a new async function to a given name. The await keyword is permitted within the function body, enabling asynchronous, promise-based behavior to be written in a cleaner style and avoiding the need to explicitly configure promise chains.

Async/await - The Modern JavaScript TutorialThe word “async” before a function means one simple thing: a function always returns a promise. Other values are wrapped in a resolved promise automatically. For instance, this function returns a resolved promise with the result of 1; let’s test it: async function f() { return 1; } f().then(alert); // 1.

Understanding (and effectively using) asynchronous JavaScriptUsing async JavaScript, you can perform large functions without blocking the main thread of JavaScript. To better understand this, let’s look at what we mean by synchronous and asynchronous JavaScript. Synchronous JavaScript as the name implies, means in a sequence, or an order.

Async/await - JavaScriptLe mot “async” devant une fonction signifie une chose simple : une fonction renvoie toujours une promesse. Les autres valeurs sont enveloppées dans une promesse résolue automatiquement. Par exemple, cette fonction renvoie une promesse résolue avec le résultat 1 ; testons-la: async function f() { return 1; } f().then(alert); // 1.
