What does "async / await" mean in programming?
async / await is one of the most common terms in software development. This guide explains what it means, how it is used in practice, and why it matters, with real examples from the developer world.
Definition
A syntax for writing asynchronous code that looks synchronous. An async function always returns a Promise. The await keyword pauses execution inside an async function until the awaited Promise resolves, without blocking the thread. Supported in JavaScript, Python, Rust, C#, and others.
Example
"async function getUser(id) { const user = await db.findById(id); return user; }"
