Article Introduction：In this article, we will learn about the difference between “for” loop and “while” loop. For Loop A for loop is a control flow statement that executes code for a predefined number of iterations. The keyword used in this control flow statement is "for". Use a for loop when the number of iterations is known. The for loop is divided into two parts - header - this part specifies the iteration of the loop. In the header section, the loop variable is also declared, which tells the body which iteration is being executed. Body - The body section contains the statements that are executed for each iteration. Initialization, condition checks, and iteration statements are all written at the beginning of the loop. Use it only when the number of iterations is known in advance. If no condition is mentioned in the 'for' loop, the loop will iterate infinite times. Initialization only takes place once

Article Introduction：Difference: 1. for loops through each data element through the index, while forEach loops through the data elements of the array through the JS underlying program; 2. for can terminate the execution of the loop through the break keyword, but forEach cannot; 3. for can control the execution of the loop by controlling the value of the loop variable, but forEach cannot; 4. for can call loop variables outside the loop, but forEach cannot call loop variables outside the loop; 5. The execution efficiency of for is higher than forEach.

Article Introduction：Why can't we add or delete collections when enhancing the for loop in java? A loop iteration has nothing to do with the addition, deletion and modification of the collection. Modifying the collection is not done by for. for only loops iterations. You modify the collection in the loop, change the length of the collection, and the order has an impact on the loop.

Article Introduction：When I was writing code today, some inexplicable things appeared when I used a for-in loop to traverse the array. I checked the information later. Only then did I know the difference between for-in loop and for loop. The for -in loop is iteration. It iterates all the properties and methods of the current object. It will filter out the properties and methods originally written by the system. If we add properties and methods to it. During for-in, these properties and methods we added will be traversed. For example: I added a method //Array to array in js

Article Introduction：We use JavaScript's for loop statement to repeat a set of statements in the loop body a specified number of times. Nested for loops, as the name suggests, are composed of multiple for loops, with one loop nested inside another loop. This allows us to loop over multidimensional data structures such as matrices. Nested for Loops in JavaScript A simple for loop executes a specified number of times based on initialization values ​​and termination conditions. Nested for loops, on the other hand, have one or more for loops residing inside the outer for loop. Syntax for(leti=0;i<limit;i++){//statement}This will create a simple for loop that executes limit times. this means
