|
|
* ```JavaScript

* // Calculate state objects initial hash
|
|
* const hash = calculateChangeHash(state);
|
|
*
|
|
* // Process the received activity
|
|
* await processActivity(context, state);
|
|
*
|
|
* // Save state if changed
|
|
* if (calculateChangeHash(state) !== hash) {
|
|
* await storage.write({ 'botState': state });
|
|
* }
|

* ```
|
|
* @param item Item to calculate the change hash for.
|
|
* @returns change hash string
