What is balancer V2?

So, can you tell me, what exactly is Balancer V2? I've heard a lot about it in the crypto space, but I'm still not entirely clear on what it does or how it works. Is it a new type of decentralized exchange? Or is it a token? And what makes it different from other similar platforms out there? I'm eager to learn more and understand how it could potentially fit into my investment strategy.
