:mrdocs:

Print onto the stream supplied at construction the sequence of characters designating the start of an array (referred to as an "array" in JSON) with the specified `name`, preceded, if necessary, by a comma. Optionally specify `formattingStyle` denoting if the array being opened should be formatted as an empty array. If `formattingStyle` is not specified then the array being opened is formatted as a regular array having elements. The behavior is undefined unless `isNameNeeded()` is `true`. Note that the formatting (and as a consequence the `formattingStyle`) is relevant only if this formatter encodes in the pretty style and is ignored otherwise.
