In this haste 5e spell you need to choose any of your willing creature which you can able to see within a range. Until unless the spell ends, the target’s speed would be doubled, it actually gains a +2 bonus to AC, it has an advantage on a dexterity saving throws, and it also gains an additional action on each of its turns. So, that action can be used for the sake of take the attack (but one weapon attack only), Dash, Disengage, Hide, or else Use an Object action.
Whenever this haste spell 5e ends, then the target can not move or can not take an action until after its next turn, like a wave of lethargy sweeps over to it.
