Javascript beautifier (https://beautifier.io/)

Usage: jsbeautifier.py [options] <infile>

    <infile> can be "-", which means stdin.

Input options:

 -i,  --stdin                      Read input from stdin

Output options:

 -s,  --indent-size=NUMBER         Indentation size. (default 4).
 -c,  --indent-char=CHAR           Character to indent with. (default space).
 -e,  --eol=STRING                 Character(s) to use as line terminators.
                                   (default first newline in file, otherwise "\\n")
 -t,  --indent-with-tabs           Indent with tabs, overrides -s and -c
 -d,  --disable-preserve-newlines  Do not preserve existing line breaks.
 -P,  --space-in-paren             Add padding spaces within paren, ie. f( a, b )
 -E,  --space-in-empty-paren       Add a single space inside empty paren, ie. f( )
 -j,  --jslint-happy               More jslint-compatible output
 -a,  --space-after-anon-function  Add a space before an anonymous function's parens, ie. function ()
 --space-after-named-function      Add a space before a named function's parens, i.e. function example ()
 -b,  --brace-style=collapse       Brace style (collapse, expand, end-expand, none)(,preserve-inline)
 -k,  --keep-array-indentation     Keep array indentation.
 --quiet                           Suppress info about a file if nothing was changed.
 -r,  --replace                    Write output in-place, replacing input
 -o,  --outfile=FILE               Specify a file to output to (default stdout)
 -f,  --keep-function-indentation  Do not re-indent function bodies defined in var lines.
 -x,  --unescape-strings           Decode printable chars encoded in \\xNN notation.
 -X,  --e4x                        Pass E4X xml literals through untouched

 -m,
 --max-preserve-newlines=NUMBER    Number of line-breaks to be preserved in one chunk (default 10)
 -O,  --operator-position=STRING   Set operator position (before-newline, after-newline, preserve-newline)
 -w,  --wrap-line-length           Attempt to wrap line when it exceeds this length.
                                   NOTE: Line continues until next wrap point is found.
 -n,  --end-with-newline           End output with newline
 --indent-empty-lines              Keep indentation on empty lines
 --templating                      List of templating languages (auto,none,django,erb,handlebars,php,smarty) ["auto"] auto = none in JavaScript, all in html

Rarely needed options:

 --eval-code                       evaluate code if a JS interpreter is
                                   installed. May be useful with some obfuscated
                                   script but poses a potential security issue.

 -l,  --indent-level=NUMBER        Initial indentation level. (default 0).

 -h,  --help, --usage              Prints this help statement.
 -v,  --version                    Show the version
