* Calculates the exponential delay based on the current retry attempt.

|
* @param {number} currentRetry - The current retry attempt number.
|
* @returns {number} - The calculated exponential delay in milliseconds.
|
*
|
* The delay is calculated using the formula:
|
* - If `currentRetry` is 0, it returns the minimum backoff time.
|
* - Otherwise, it calculates the delay as the minimum of:
|
* - `(2^(currentRetry - 1)) * deltaBackoff`
|
* - `maxBackoff`
|
*
|
* This ensures that the delay increases exponentially with each retry attempt,
|
* but does not exceed the maximum backoff time.
