In single-threaded JavaScript, asynchronous execution is managed via callback functions. Consider how operating systems handle interrupts: while a peripheral device completes I/O, the CPU continues other work until an interrupt signals completion. Callbacks operate on a similar principle—the runtime...
To test your understanding of async/await behavior in the JavaScript event loop, try these two similar snippets first: async function runFirstTask() { await new Promise((resolve, reject) => { resolve(); }); console.log('A'); } runFirstTask(); new Promise((resolve) => { console.log('B'); resolv...
