This code processes tasks from a queue until all tasks are completed. The while loop continues as long as there are tasks in the array. Each iteration removes and processes the first task. This pattern is common
If you have read the previous chapter, about the for loop, you will discover that a while loop is much the same as a for loop, with statement 1 and statement 3 omitted. The loop in this example uses aforloop to collect the car names from the cars array: ...
...WHILE [ > ] WHILE expression LOOP statements END LOOP [ label ]; 只要条件表达式为真,其块内的语句就会被循环执行...[ > ] FOR record_or_row IN query LOOP statements END LOOP [ label ]; 这是另外一种形式的FOR循环,在该循环中可以遍历命令的结果并操作相应的数据...
The following example demonstrates the basic usage of thedokeyword in a do...while loop. main.js let i = 0; do { console.log(i); i++; } while (i < 5); This loop will execute the code block first, then check if i is less than 5. It continues looping while the condition is ...
The while loop calculate the sum of odd numbers between 0 to 10. List of numbers : JS Code var x = 1; var y = 0; var z = 0; document.getElementById("result").innerHTML = "List of numbers : "; while (x <=10 )...
在上面的示例中,我们定义了一个名为delayedWhileLoop的函数,它接受三个参数:condition(条件函数)、action(执行函数)和delay(延迟时间)。函数首先检查条件函数的返回值,如果为真,则执行执行函数,并在延迟时间后再次调用delayedWhileLoop函数。这样就实现了延迟执行While循环的效果。
