What is snapchat is typing notification?

When two Snapchat users are communicating with each other in a chat, typing notifications show up when one of the users is actively typing. This feature is similar to other messaging apps such as iMessage or Facebook Messenger. The typing notification appears as three dots, which is displayed on the chat screen beside the name of the person who is typing. It allows the user to know that someone is actively engaging with them on the other end of the chat, and it helps to create a more real-time conversation experience. However, this feature can be disabled by the user in the app's settings.
