jQuery deferreds and promises - .then() vs .done()

Question

I\'ve been reading about jQuery deferreds and promises and I can\'t see the difference between using .then() & .done() for successful callbacks

Answer 1

There is a very simple mental mapping in response that was a bit hard to find in the other answers:

• done implements tap as in bluebird Promises

• then implements then as in ES6 Promises
