  Sets the ECMAScript version to parse. Default is version 7.

- FC**--tokenize**F\[0\]

  Tokenizer mode of the parser.

- FC**--locations**F\[0\]

  Attaches a "loc" object to each node with "start" and "end" subobjects, each of which contains the one-based line and zero-based column numbers in {line, column} form.

- FC**--allow-hash-bang**F\[0\]

  If enabled, skip the leading hashbang line.
