In JavaScript, theforloop can be achieved in different ways -for,for...in,for...of, andforEach- which are useful for different case scenarios.for..ofallows us to access the element of the array directly without having to use any index value which is typically inserted into the array squ...
In this Python tutorial, you will understandPython for loop with index. I use the for loop with index while iterating over the iterable object to reverse the item of the iterable object. But you can’t access that index using the Python for loop only; you will need to tweak the for lo...
JavaScript var nums = [1, 10, 5, -9, -1]; for (var i = 0; i < nums.length; i++) { console.log(nums[i]); } Once again, the loop's counter i begins at 0 since the index of the first array element is 0. The counter goes upto nums.length (excluding it), being incremen...
Running the JavaScript code above will result in the following output. Output [ 0 ] [ 0, 1 ] [ 0, 1, 2 ] We set a loop that runs untili < 3is no longertrue, and we’re telling the console to print thearrayExamplearray to the console at the end of each iteration. With this ...
async/await方法:loopWithIntervalAsync函数是一个异步函数,它使用for循环来迭代,并在每次迭代后使用await delay(interval)来暂停执行,直到定时器到期。这种方法代码更加简洁,且易于理解和维护。 应用场景 这种间隔执行的循环在需要定时执行任务的场景中非常有用,例如: ...
