I have a number of enumerables, and I want to randomly pick one value from one of the enumerables so that each value has a certain weight in the randomisation process. This is simplification of my current code:
private enum ActionPlan //Just an example, there can be many different enums

I was able to get some very helpful code to get tuple values on a previous question. I was able to reduce my duplication a lot. But I'm having trouble wrapping this code in its own helper class so it can be reused in other classes.

twiddle_real[i] = (float) cos((float)i * 2.0 * PI / (float)N);

Whenever I use the ternary operator, it is always in the following context:
const someResult = someVar ? "opt1" : "opt2";
A colleague of mine is a bit more "flexible" with the ternary operator:
for (let key in someColl) {
arr[key] ? arr[key]++ : arr[key] = 1;
}
Aswell as:

Similar to other GTIN validations, the function should take the entire string of the read in barcode, calculate the check digit, and compare it to the check digit on the code. For example, the code 6291041500213 would take the first 12 digits (629104150021) and calculate the answer of 3.
