Right, I do that too. The real problem is the development lifecycle for a lambda. It's a constant loop of changing the code, building it and then invoking it.

Right, I do that too. The real problem is the development lifecycle for a lambda. It's a constant loop of changing the code, building it and then invoking it. This process takes a bunch of seconds even for the smallest change in a tiny code base. It's much slower than writing code and immediately going to a browser to reload to see the changes which is something a lot of dev environments were able to pull off since about 1998.
