Edit Question
Title
Body
We have received some JavaScript from an agency that looks wrong, but works. For some reason they are adding square brackets ( [ , ] ) around variables, like this: var some_variable = 'to=' + [other_variable]; This works, but the square brackets seem completely superfluous. Is there a purpose of using this syntax or is it technically incorrect, but ignored by the browser?
