What's the difference between laughing and joking? Can you give me an example?

The difference between ridicule and joking is that:

Laughing is ironic, and the expression will make people uncomfortable. For example, people who laugh at you for being fat will say: You should eat even if you are so fat! Do not look at yourself!

Jokes are mostly well-intentioned, which will make us laugh it off without discomfort. For example, people who joke that you are fat will say: For your health, so give me the meat in your bowl and eat more vegetables!
