How is JTBD different from features, personas, or user needs?

The short answer

Personas describe who; JTBD describes the progress they're trying to make and the struggle that pushes them to switch. Features are your answer; the job is their question. Anchor on the job and your features stop being a wishlist and start being a solution to something real.
