Asynchronous JavaScript?

JavaScript can start a task and continue executing other code without waiting for that task to finish.

Example:

console.log("Start");

setTimeout(() => {
console.log("Hello");
}, 2000);

console.log("End");

Output:

Start
End
Hello

Here, setTimeout() schedules the callback to run after approximately 2 seconds. JavaScript continues to the next line instead of waiting.
