What are the differences between MTG interrupts and instants, and how do they impact gameplay in Magic: The Gathering?

In Magic: The Gathering, interrupts and instants are both types of cards that can be played at any time, but interrupts can only be played in response to specific triggers, while instants can be played at any time. This impacts gameplay by allowing players to strategically respond to their opponent's actions or change the course of the game in their favor.
