error A callback to execute if FileReader encounters an error. The function should receive two arguments: the error and the File.download If true, this indicates that the string you passed in is actually a URL from which to download a file and parse it.keepEmptyRows If true, rows that are empty will be included in the results as an empty array. This is useful if you want to maintain line (or at least row) parity with the original input.skipEmptyLines If true, lines that are completely empty will be skipped. An empty line is defined to be one which evaluates to empty string.chunk A callback, much like step, which activates streaming and is executed after every whole chunk of the file is loaded and parsed, rather than every row. Works only with local and remote files. Do not use both chunk and step callbacks together. As arguments, it receives the results, the streamer, and if parsing a local file, the File object. You can pause, resume, and abort parsing from within this function.fastMode When enabled, fast mode executes parsing much more quickly. Only use this if you know your input won't have quoted fields.
