![]() So, in order to rewrite your function we have to take this into account. So, in order to rewrite your function we have to take this into account. The fundamental difference is that sleep (as used in many other languages) is synchronous, while setTimeout (and many other JavaScript-concepts, like AJAX for example) are asynchronous. You just need to await on a promise that resolves after a given period of time. However, you can pause an async function call without blocking the rest of the JavaScript runtime. The fundamental difference is that sleep (as used in many other languages) is synchronous, while setTimeout (and many other JavaScript-concepts, like AJAX for example) are asynchronous. Since JavaScript is single-threaded, C-style sleep (2) would block the entire JavaScript runtime for 2 seconds, and that isnt very useful. I dont fully understand what you're asking, but I'm going to answer this part: while (curr - start < time) is tricky, but it won't work (just stops my browser and then throw all console logs at once). ![]() ![]() + fib(n)) and sleep after every "+"? Nah, sleep would be muuuuuch easier.īut still I can't get working example of implementing it. ![]() If you know how to get the same result using setTimeout - tell me ) fibanacci is pretty easy task, because there aren't more than 2 recursions, but how about n-recursions (like fib(1) + fib(2) +. wait 1 second before announcing the result wait 1 second before computing for lower n For example, if you use PHP language, you should call sleep () function to make the program pause execution for 3 seconds. please, don't tell me about setTimeout method because - yes, everything is possible with that but not so easy as using sleep() method.Ĭonsole.log("Computing Fibonacci for " + n + ".") What is JavaScript Version of Sleep () Programming languages have their way of making the program stop for some seconds or milliseconds. Each setTimeout creates an asynchronous code that executes after the given delay time. Yes, I know - that question has thousands of answers. The setTimeout function can be used to make a JavaScript sleep or wait method.
