Excellent video. I like the explaination of a " a 2d array is a bunch of 1d arrays" and 3d array "is a bunch of 2d arrays"

I finally understood the 3D array. It was really helpful the way you illustarted it. Really appreciated.

[jonathangodson]

The way you illustrated it is the best i have come across. Thank you

dude I was reading course materials as well as browisng around and your explanation really helps my dumb brain understand it, thank you so much.

I couldnt thank you enough to explain 3D arrays. This was so clear that i have no doubts left. People make square brackets and then enter value this was so good and easy to understand. Thank you.

I spent 2 hrs on other yt videos understanding 3d and higher arrays but none give as clarity as you did in those 3, 4 minutes. Great stuff:)

Appreciation note:
After reading and watching tons of things on 3-D arrays
Finally I got this video which made me clear what it actually is
thank you....

[MarharytaKalynchuk]

Thank you for this super illustrative explanation! I should check some of your other videos.

Wow this is short seet and simple...My head was spinning and couldn't visualize how matrixs make 3d arrays

[krishshah]

Also i saved this video in my notion. <3

[Kabeer]

thanks a ton for explaining it so well!

[Copybook]

Most internet contents are useless, man. This video saved my hours. Thanks

It would be easier to understand, if you could talk in coordinates instead of vector (although I understand that vector [2, -3, 1] has certain x, z, y -coordinates). However, when defining a matrix it would be more helpful to give an example of matrix that has 5 cells in x-axis, 4 cells in y-axis and 3 cells in z-axis. When you explain this with vector coordinate system, you are losing about 95% of your audience.
