Compiled Code Balance

A natural consequence of writing typed code (at least today) is depending on a build step, which is the case for the vast majority of us.

Build Step Advantages

If we did want to envision a build-less future, the first step would no doubt be native type support in JavaScript.

What do you feel are the main advantages resulting from using a build step?
