This is misleading: the {} is interpreted as an empty code block instead of an empty object, and the empty array is cast to a number by the remaining unary + operator. If you wrap the expression in parentheses ({} + []) the curly brackets are interpreted as an empty object and the result of the expression is "[object Object]" as expected[37]. And as @Jochem points out below, you may want to use encodeURIComponent() on a (each) folder name, but for whatever reason these APIs don't seem to want + in folder names so plain old encodeURIComponent works great.
