javascript do while loop delay

; If the condition evaluates to true, the body of the loop inside the do statement is executed again. I have looked all over and everywhere people are mentioning setTimeout, but that only causes a delayed start of a function.. Please see the do while loop , i have added that because i have to wait until a timer expires and _stMinExpired is set to true. do statement while (condition); statement A statement that is executed at least once and is re-executed each time the condition evaluates to true. Node can do nothing while this loop is ticking. In contrast to the break statement, continue does not terminate the execution of the loop entirely. The function delay(ms) should return a promise. ; The condition is evaluated once again. The built-in function setTimeout uses callbacks. Method 1: Using an infinite loop to keep checking for the elapsed time The time that the sleep function starts is first found using the new Date().getTime() method. That promise should resolve after ms milliseconds, so that we can add .then to it, like this: Then the condition is evaluated. An infinite while loop is started. The 1e10 is 1 with 10 zeros in front of it, so the loop is a 10 Billion ticks loop (which basically simulates a busy CPU). Each call remembers the real time from the previous one in the times array. This means awaits in a for-loop should get executed in series. condition An expression evaluated after each pass through the loop. To execute multiple statements within the loop, use a block statement ({ ... }) to group those statements. Await in a forEach loop. Create a promise-based alternative. The delay parameter you pass to these functions is the minimum delay time to execute the callback. We'll do the same thing as we did in the for-loop example. JavaScript wait() To make JavaScript wait, use the combination of Promises, async/await, and setTimeout() function through which you can write the wait() function that will work as you would expect it should. This flag is set when a System.threading.timer expires. Just like JavaScript for, for in, do, do while loops. Essentially in JavaScript there is no way to pause a running loop. 'Start' 'Apple: 27' 'Grape: 0' 'Pear: 14' 'End' This behaviour works with most loops (like while and for-of loops)… When you use continue without a label, it terminates the current iteration of the innermost enclosing while, do-while, or for statement and continues execution of the loop with the next iteration. The setTimeout call in it re-schedules itself with zero delay. We'll look at how await affects forEach, map, and filter in the next few sections. Like above example we set a delay to display a message for a spacific times. But it won't work with loops that require a callback. I just want to slow my for loop so you can visually notice each iteration. The code works fine and does what I want it to do, but the for loop executes so quickly that you don't notice the change in opacity. The continue statement can be used to restart a while, do-while, for, or label statement.. ; If the condition evaluates to true, the body of the loop inside the do statement is executed again. ; This process continues until the condition evaluates to false. Then only i should send next frame. In the browser, there’s a limitation of how often nested timers can run. We'd like a delay in between. Here, The body of the loop is executed at first. When you use await, you expect JavaScript to pause execution until the awaited promise gets resolved. The HTML5 standard says: “after five nested timers, the interval is forced to be at least 4 milliseconds.”.. Let’s demonstrate what it means with the example below. This returns the number of milliseconds passed since the Epoch time. However, you can only call this custom wait() function from within async functions, and you need to use the await keyword with it. This of course is a very bad thing to do in practice, but it’ll help you here to understand that setTimeout delay is not a guaranteed thing, but rather a minimum thing. The result is what you’d expect. Examples of such loops that require a fallback include forEach, map, filter, and reduce.
