An easier way to iterate through a loop is via the for loop, which we’ll talk about in this JavaScript tutorial. A for loop does exactly the same thing as a while loop, but it has the advantage of organizing it’s components more locally and neater.
As always, if you have any questions, fire ahead with them below :).

What would be a typical usage case where a "for" loop would be preferable to using a "while" loop, other than to reduce clutter? Thanks again for the great content!
everything's better explained in british accent
Very helpful – thanks!!
Ivan brought me here.
It didn't work for me, And I don't know why.
it's very short explain it's not good for professional

Can you add another video showing different problems utilizing the for loop?
I gave each element an id assignment because the console read an error for getElementByTagname The console logged 5 links and printed out.
Why we right '+ i' in consol.log?
Couldn't we just say 'i'?
I need help. Do you know how to turn off errors that are showing in brackets (probably new version) in js files on some codes which are absolutely correct. I just done the same code that is in the videos but those red circle errors keep showing on some codes.
when a C programmer see this XD::
for(;;){console.log("I hate web programming !");}
error are appearing please help!
When I put '"links.length" nothing shows up on my screen, but the moment I change it into a number; the loops show up. lol?
your videos are so easy to understand. Can you please do an example of how to create the game hangman using JS? Or other games?
I have a question that has been bugging me for some time now. If I wanted to use the variable i inside the loop, to let's say push an 'input to the alert' into an array of objects, how would I go about that?
Great tutorials lads. Nothing better than showing 'actual examples' like looping through links, then just going over the fundamentals.
Thank you so much for this I really appreciate the time and effort you put into these vids.
I am using brackets and typed in the code, verbatim, with the following errors JSLint (6)3'i' was used before it was defined.for (i = 1; i < links.length; i++) {3Unexpected '++'.for (i = 1; i < links.length; i++) {3Unexpected '(space)'.for (i = 1; i < links.length; i++) {5'console' was used before it was defined.console.log("this is link number" + i);9Expected 'document' at column 1, not column 3.document.write("all liks are looped");Help?
You do need 'var' keyword for 'for' loop variable, otherwise you create a global variable which remains while page lives. Let alone cases when you recursively call a function containing 'for' loop. And if you use ECMA6 then 'let' variable is even better for 'for' loop.
hi there, great videos, really learning alot from your playlist of this series. Just a quick question, you dont seem to be using var to declare the new variables within the for loops, the code still seems to work, so just wanted to confirm, is var not required within the for loop or is it good practice to use it. e.g. you did:
– for (age = 5; age < 10; age++) however should i be doing:
– for (var age = 5; age < 10; age++) instead.
Thanks again.
thank you for all the info man… btw what type of text editor is that? look amazing!
