This is such an underrated gem of a video. There are no videos explaining the rather obvious stuff but it's difficult for a beginner to find them... Thank you.

Great tutorial, touching what is just necessary to get started.
By the way the calculation of perimeter is wrong, it should be 2 * r.width + 2 * r.height

Thanks for the clear video. Helped a lot


btw the perimeter formula is 2*width +

Thank you for these Go tutorials! They are great and it would be awesome to see more of them! Data structures implementation maybe :) ?

Hello...Great tutorials!!You helped me clarify a lot of things...On this one though i have a question..If i take out the pointer in the perim method (e.g -->func (r rect) perim() ), i get the same results. Any thoughts?...Thank you

I thought that methods can be added to custom type even if it is not struct. For insurance type number int. We .can easily add methods here.

[shamikchakraborty]

what is the difference between Functions and Methods ?

[amlanch]

Perimeter formula is incorrect. It’s 2 * (h +w)

Why would you use a pointer as input in this case? I don't see the benefit.
