why use reloadRows in beginUpdates and endUpdates

Question

in many other posting, they use only reloadRows between beginUpdates and endUpdates.

like this

self.tableView.beginUpdates()
self.tableView.reloadRows(at: [indexPath], with: .fade)
self.tableView.endUpdates()

but when i use this way and use only reloadRows without beginUpdates and endUpdates, i dont know any difference.

why use reloadRows in beginUpdates and endUpdates??

It's just a bad practice which doesn't hurt.

There is no reason at all.

beginUpdates() / endUpdates() are useful for multiple simultaneous insert/delete/move operations.

The methods have no effect for a single operation and are completely useless for calling reloadRows
