Golang versus Type Script

I was doing a very basic hacker rank for summing the diaganols of a matrix with n number of rows and columns.

Turns out... the Hacker Rank had incorrect directions. I needed to write code just to test the directions. So I ended up writing the solution in two different languages.

Go, Javascript

But... I ran into Go missing a lot of features like basic checking for an array element. There is a ton of boilerplate needing written.

So I decided to try facing Node's notorious silent errors. But I used Type Script.

That is how I learned the inputs from hacker rank were wrong. When I wrote tests and checked types.
