Hey @kh0alu, thanks for submitting this. I believe your question is more related to JavaScript than Truffle itself but I'll gladly answer it for you here! When looking to get the length of an array you can use the .length method to get the result.

For example

const fruits = ["Banana", "Orange", "Apple", "Mango"]; let length = fruits.length;

If we were to console.log(length) the result would be 4. Hope this helps. If I doesn't address your issue feel free to ask again here and we'll gladly help out however we can. Thanks!
