typescript recordtype add items dynamically

Question

I need to store the following data in any structure.

"Total Count": "Error Count": "Success Count":

The keys are known upfront, however the values will only be determined at different stages in the processing cycle. What is the best data structure which I can use to store this data. I can convert the keys to an enum and use the record type but not sure how to proceed from there.

Answer 1

If I understood your need:

type DataCount = Record<'total' | 'success' | 'error', number>;

const sample: DataCount = {
  total: 0,
  success: 0,
  error: 0
}

// increment count
