Thanks, I had no clue of some differences between TypeScript and javaScript

error TS2339: Property 'itemsPerPage' does not exist on type 'PaginationHelper'.

constructor(collection, itemsPerPage){
this.itemsPerPage = itemsPerPage
}

isn't it how we declare variable and assign it to the constructor parameter?
using vscode all codes are working just fine. but here I'm stuck with this code.

anybody with a brilliant idea?

Fantastic work!, Mine has almost the same procedures as yours, but too manuel.
I knew I needed recursion; I wasn't able to transform my function into a recursive one.
So, thank you.

If you have difficulties on understanding the kata, this means you need to learn algorithm first.
I decided to go back and deepily learn algorithm. I haven't finish the lesson yet but as I go on, I begin to see the kata(s) that seemed ambiguous to me from different algorithm approaches that I'm learning now.

Each kata or problem as its relevant algorithm to solve it.
here is the link that may help you learn algorithm https://www.youtube.com/watch?v=8hly31xKli0

Hello guys, to whom may have encoutered the execution time error. (Your codes take too much time to execute even though you solved the problem)

This made me come to realize that this platform codewars isn't about statistics or proving how master you are in coding. it's about learning and improving your programming skill.
Therefore, It all comes down to "algorithm", the first 15 minute of this video https://www.youtube.com/watch?v=8hly31xKli0 will blow your mind.

I've got issue with the time execution whenever I click on the attempt button.
Does it mean that I have to find another way to tackle the kata? The one with less execution time?

To be honest, the problem I have lies on what makes a walk. Is the total directions we have in array list? as it says you walk only one block for each direction and it takes 1 minute to traverse a city block.
