acorn is a utility to parse a JavaScript file from the

the syntax tree as JSON data.
- --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
