What is snapchat is typing?

Snapchat is an instant messaging app that allows users to share photos and videos that disappear after they have been viewed. The app also offers a typing feature that allows users to send messages that will be displayed in text form instead of as a photo or video. The typing feature is similar to other messaging apps, and allows users to have real-time conversations with their friends. Users can also see when their friends are typing, which indicates that they are currently composing a message. This feature helps users to know when to expect a response and allows for more seamless communication.
