Communication is a central part of working in teams. I believe having asynchronous communication channels and making heavy use of them can have great effects on productivity, transparency and therefore happiness and fun within teams. Here are a few reasons why.
There are dozens of studies about the consequences of being interrupted while performing demanding tasks. They usually suggest that it takes a human around 20 minutes to get back into the state they have been in prior to the interruption. As if this wouldn't be enough it also increases the chances of making mistakes.
While a chatroom doesn't necessarily removes interruptions all at once it allows everyone to react to an interruption at will. If you really want no interruption for a certain period of time you can easily turn off all notifications. Not reacting to the waving hands of a coworker is quite a bit harder (and not very polite as well).
Transparency is a great thing. I strongly believe an absolutistic approach to transparency is the only way to go nowadays. Transparency helps to identify bad decisions early on and increases acceptance of decisions by keeping everyone in the loop. Companies like Stripe are doing an excellent job at advocating this approach. I could go into lengths about how important this is.
Achieving this level of transparency with meetings and written reports is very time consuming if not impossible at all. Channeling most communication through asynchronous communication channels allows other people to passively follow along and saves a bunch of time that would otherwise have been spent in inefficient meetings.
Think before you speak. That's what they say. Problem is that this is quite hard in a fast paced environment like meetings. Just taking 5 minutes to order your thoughts isn't something people usually do there. Instead they talk. Written communication forces you to get to the point in a way that everyone can follow and at the same time allows you to refine your own understanding of the problem.
Most of the team chat things you'll find provide integrations with your existing toolchain. It's easy to setup a bot that notifies you about breaking builds, new commits, errors on your platform or whatever else. Integrating this kind of information into your communication channels allows better collaboration on it and also increases visibility of what people are working on (= transparency).
In my experience things are often discussed in passing and sometimes even decisions are made in these situations. A week later when you actually find the time to implement the things decided back then they seem stupid and you are not able to actually retrieve the reasoning behind them from the back of your head. Having in place the infrastructure to quickly discuss something without setting up a meeting is a great way to avoid this kind of decision making and also allows you to trace back past discussions if a decision is being questioned.
Channeling most conversation through chat rooms makes team members less dependent on being geographically close to each other. (I'm not expanding on this as I think removing a dependency is always a good thing.)

I'm a strong believer when it comes to asynchronous communication and I hope this list provides a good overview about the main reasons why it's a good approach to internal communication.
