It doesn't matter how cool the slice notation is when people have trouble accessing single elements! 1 based is better for human counting and 0 is better for certain mathematical expressions, usually when thinking about offset from the start rather then list position. Clearly it is a judgement call, but I personally think counting is more important for the same reason PI is wrong. We are confusing ourselves because easy things aren't intuitive. Imagine you have: var list = ['first','second', 'third'] `list[2]` should clearly be the second element (not third), just as PI / 2 should mean half a circle (not 1/4). We wonder why there aren't as many computer science / math grads. Well in every intro class in the world people are getting confused by this.
