What is what does haha mean in text message?

"Haha" is an expression used in text messages or online communication to indicate laughter or amusement. It is a shorthand way of conveying a humorous response without typing out a full statement. When a person types "haha" in a message, it indicates that something has amused them, but not necessarily that they are laughing out loud. The amount of "ha" letters following each other could signify the level of amusement from the person. For example, "haha" may indicate a small degree of amusement, while "hahahaha" may indicate a higher level of amusement elicited by the message.
