For instance, if we want to print 'Hello' a thousand times, or display a multiplication table for an arbitrary integer showcasing multiples from 1 to n, what we need is the for loop. In both of these cases, we know the limit to the iteration in one way or the other. Compare this ...
In awhileloop, the condition is tested, and if it is true, the loop is executed again In afor loop, the increment expression (e.g. i++) is first evaluated, and then the condition is tested to find out if another iteration should be done ...
Click me let b = document.querySelector("#mybutton"); b.onclick = function() { console.log("Thanks for clicking me!"); }; b.addEventListener("click", () => { console.log("Thanks again!"); }); 调用addEventListener()时,第一个参数为“click”不会影响onclick属性的值。在此代码中...
We got a syntax error because theforEachloop behaves more like a function than a loop. That is why you are unable to continue performing on it. However, if you must usecontinuein aforEachloop, there is an option. Areturnmay be used to exit theforEachloop. ...
When JavaScript encounters acontinuestatement in a loop it stops the execution of the current iteration and goes back to the beginning of the loop to begin the next iteration. The example below displays only even numbers. copy for(vari=1;i<=10;i++){if((i%2)!=0){continue;}console.log...
If the evaluation result istrue (xhs < xhsLength), the loop body is executed. Therefore, the loop body may not be executed. If the body of the loop is executed, the expression will be executed after the loop to increment the variablexhs.forcycle with the followingwhilecycle is the same...
Async generator functions are similar to generator functions, with the following differences: When called, async generator functions return an object, anasync generatorwhose methods (next,throw, andreturn) return promises for{ value, done }, instead of directly returning{ value, done }. This automa...
Thecontinuestatement breaks one iteration (in the loop), if a specified condition occurs, and continues with the next iteration in the loop. This example skips the value of 3: Example for(leti =0; i <10; i++) { if(i ===3) {continue; } ...

For example, you might be stepping through a loop in a function and determine that the code in the loop is performing correctly. Rather than stepping through every iteration of the loop, you can run to the cursor that is positioned after the loop is executed. Sometimes, it's difficult to...
