Short way to let a person know over text that they are laughing/thought something you said was funny. It however doesn't really reflect how much they are actually laughing/how much they actually thought something you said was funny.
Haha that's awesome!

Definition 1:
Haha - used to express laughter anywhere you can't say it, for example IM, instant messaging or via email.

The minor difference between haha and hehe is that haha is often used when laughing at someone, while hehe is used while laughing with someone. It might be unconcious to most people, but it's true.

Definition 2:
Ha-ha - when haha is pronounced like 'Ha-ha', it often expresses that one do not find something humourous; ironic.

I also found some pretty random ancronyms for haha online:

Having A Heart Attack
Houston Area Hound Association (Texas)
Human-Anti-Humanized Antibodies (immunogenicity testing assay)
Example 1 (haha): You don't know who Shakespeare was? Haha!
Example 2 (ha-ha): Ha-ha, how funny!
Example 3 (hehe): Hehe, you're so funny!
