Tricky JS Loops

I'm having difficulty understanding the logic behind the answer in the following loops. Can someone explain in details, what is going here? Thank you, in advance! https://code.sololearn.com/WoEo8N12nCP5/?ref=app

Thank you for your help. I still don't get the 2nd example. I copied the loops from the JavaScript challenges. Those were the answers that were given at the end of the challenges.

Both the answer written as a comment is wrong the value of i for the first for loop will be 6 let see k= 6; for(var i =0; i<k; i++){ k+=0 //it means k= k+0; } As you can see for i=0 k=6+0=6 i=1 k=6+0=6 .. similarly when i=5 k= 6+0= 6 Now I will increase by 1 it means now i=6as it is going on then it will check the condition i<k that is 6<6 which is wrong hence for loop stops executing and we will get the value of i as 6 same method for the 2nd for loop you can apply If you get this..do comment
