Feel free to assign me. w3School seems to have the beginner-friendly content similar to what you are developing. So , would it be okay to reference their page for a tutorial?

[funbeedev]

@beheradibas you're assigned now.
Your submitted tutorial can reference the w3school tutorials but should not be an exact copy, thanks!

If this is not done, Can I take this up under hacktoberfest 2021? @funbeedev

[funbeedev]

@dilroseR Sure, you're assigned now!

@beheradibas Not sure if you still intended to work on this but you can still submit a PR on this issue! If you do we can rename your tutorial file and the repo will have 2 tutorials on while-loops.
