Why My Laptop Console Dont Show Nested Loop In Javascript

Discover the reasons why your console.log statement is not executing outside nested for loops in JavaScript. Learn about infinite loops and how to fix your

JavaScript for loop is a control flow statement that allows code to be executed repeatedly based on a condition. It consists of three parts initialization, condition, and incrementdecrement. javascript for loop begins when x2 and runs till x lt 4 for let x 2 x lt 4 x console.

The reason this is happening is because you never reset i, so the inner loop will only happen during the first iteration on the outer loop. Thereafter i will always be greater than l. Try this

Because they're nested, each loop will start at the first index every time the loop starts. In this case, the first loop, m, runs twice, the k loop four times and j loops by the number of pages multiplied by 4. i will loop three times as much. Your application is repeating the same task multiple times.

I set up a nested for loop to accomplish this but soon found it was not working, i.e. the loop stopped after a certain point. I then did some scenarios with simple nested for loops without the circle placement code and found that they were also stopping after a certain point.

Parts of a for loop The begin let i 1 The condition i lt answer The step i The body console.logi How it works The begin runs so we have an inline variable declaration here, which means i is accessible only inside the loop, we cannot access it from outside, so i 1 The begin is executed only once, during the execution of the loop it will not run again.

The outer 'for' will loop through each of 1st level arrays. So the very first outer for loop when i0 you are going to grab the first inner array 1,2 for var i0 i lt arr.length i First time through i0 so arri1,2 In the inner loop you are going to loop through each of the 3 inner arrays one at a time.

Could someone help clarify these points and explain the steps the code takes before printing the output in the console? I want to fully understand the concept of nested for loops in JavaScript, but I am unsure how to search for the right information.

The fundamental problem here is that a pair of nested loops is NOT the right approach. You need to walk a pointer through each dataset. ONE loop that advances both as needed. Note that figuring out which to advance in case of a mismatch is a much bigger problem than simply walking them through.
