I strongly agree with #1 and #2 and that is why I like typescript. It keeps things simple for me. I can look at what a function's inputs and outputs are without having to guess. I don't have to worry about having an array of strings and then someone deciding to throw a boolean in the middle. I know what all the keys on my object are and what kind of values they will contain. Code I have never looked at I can quickly figure out the structure.
