Before promises arrived natively in JS, there were(and still are) many separate independent promise implementations in the form of third-party libraries for example Q, RSVP, etc. Even jQuery has its own custom implementation that they call deferreds. The name and the implementation might differ from library to library but the intention is the same, making asynchronous code behave like synchronous code.

The Promise functionalities these libraries expose are not native JS promises. They expose their own promise api on their custom promise-like objects. We call such non-native promises as thenables IF they adhere to certain rules from the Promise/A+ specification. This adherence makes it easier for native and non-native promise implementations to play along nicely with each other.
