Difference Between while and do...while LoopThe while loop differs from the do-while loop in one important way — with a while loop, the condition to be evaluated is tested at the beginning of each loop iteration, so if the conditional expression evaluates to false, the loop will never ...
There are primarily three types of loops in JavaScript: for, while, and do...while. Below, a detailed explanation of each type with examples: For Loop The for loop iterates over a range of values using an index variable. It consists of three parts: initialization, condition, and iteration...
and you can jump to the next iteration using continue:while (true) { if (something) continue //do something else }The difference with do...while is that do...while always execute its cycle at least once.for…inIterates all the enumerable properties of an object, giving the property ...
In the second iteration, sum is a promise. (Why? Because asynchronous functions always return promises!) numFruit is 0. A promise cannot be added to an object normally, so the JavaScript converts it to [object Promise] string. [object Promise] + 0 is [object Promise]0 In the third ite...
There are several ways to iterate over things in JavaScript. Most notable way is to use loops. Loop constructs includes for, forEach, do...while, while, for...in and for...of. All these constructs loops over synchronous iterables such as arrays, objects,
This is, of course, a logical error, and you should look out for such scenarios. In JavaScript, there are four types of loops: while loops do-while loops for loops for-in loops While loops while loops are the simplest type of iteration. They look like this: var i = 0; while (i...
👊 2. Process array in sequence To wait the result we should return back to old-school “for loop”, but this time we can use modern version with for..of construction (thanks to Iteration Protocol) for better readability: async function processArray(array) { for (const item of array) ...
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 ...
