DESCRIPTION

       acorn is a utility to parse a JavaScript file from the command line.  It accepts as arguments  the  input
       file.  The utility spits out the syntax tree as JSON data.

OPTIONS

       --ecma3, --ecma5, --ecma6, --ecma7, ..., --ecma2015, --ecma2016
              Sets the ECMAScript version to parse.  Default is version 7.

       --tokenize
              Tokenizer mode of the parser.

       --locations
              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.

       --allow-hash-bang
              If enabled, skip the leading hashbang line.

       --compact
              No whitespace is used in the AST output.

       --silent
              Do not output the AST, just return the exit status.

       --module
              Indicates the code shouldn't be parsed as a script but as a module.  This influences global strict
              mode and 'import' and 'export' declarations.

       --help Print the usage information and quit.
