To implement asynchronous behavior, you can utilize a setTimeout
function within the definition of somefunc
. It's important to note that in this context, the term "asynchronous" is somewhat misleading since the function doesn't actually perform any asynchronous operations. Typically, an async function involves tasks like making network requests, processing data, and updating the DOM based on the results, often utilizing callbacks or promises to handle the response asynchronously.
In the code snippet below, we demonstrate how to schedule the execution of a function using setTimeout
:
var ns = {
somefunc: function(data) {
setTimeout(function() {
alert("hello");
}, 2000);
}
}
ns.somefunc();
When ns.somefunc()
is invoked, the function will be queued for execution after a 2-second delay. Since JavaScript is single-threaded, tasks are processed in sequence on the event queue. If there are other tasks ahead of the scheduled timeout function that take time to complete, the actual wait time may exceed the specified delay.
