@jonny Exactly. For me, the number one thing a programming language needs to do is be readable and understandable, and Javascript fails more often than not at that..

Let's say something like this was a typo (probably 99% of the cases) -- if you debug, and you have no idea what value that expression might produce, in particular if you aren't entirely certain about the value of a variable, as it would be in the real world, not a constant, your language has abandoned you.
