releaseObject

The releaseObject method is a JavaScript method that is used to explicitly release an object from memory when it's no longer needed. It is used in Office.js library to give a hint to the garbage collector that the object is no longer needed and can be cleaned up.

Syntax

object.releaseObject();

Parameters

None.

Return Value

None.

Remarks

The releaseObject method in Office.js is used to clean up and free up memory for the objects that are created during the execution of the code. The method should be called when an object is no longer needed and you want to free up the memory it's occupying.

Since the method is only a hint to the garbage collector, it doesn't necessarily guarantee that the memory will be freed up instantly. The garbage collector will take care of cleaning up and freeing up the memory at its own pace.

Example

async function releaseObjectExample() {
  const sheet = context.workbook.worksheets.getActiveWorksheet();
  const range = sheet.getRange("A1:A10");
  const values = range.values;
  
  // Use the range
  
  // Release the range object
  range.releaseObject();
}

In the example above, the range object is explicitly released using the releaseObject method. This method will free up the memory occupied by the range object and make it available for other operations.

Conclusion

The releaseObject method is an important method in Office.js library that is used to clean up and free up memory for the objects. It should be used when an object is no longer needed to optimize the performance of the application.
