[-d | --double-quotes string]
[-w | --wrap string]

DESCRIPTION
jsesc escapes strings for use in JavaScript string literals while generating the shortest possible valid ASCII-only output.

OPTIONS

-s, --single-quotes
Escape any occurrences of ' in the input string as \', so that the output can be used in a JavaScript string literal wrapped in single quotes.

-d, --double-quotes
Escape any occurrences of " in the input string as \", so that the output can be used in a JavaScript string literal wrapped in double quotes.

-w, --wrap
Make sure the output is a valid JavaScript string literal wrapped in quotes. The type of quotes can be specified using the -s | --single-quotes or -d | --double-quotes settings.

-6, --es6
Escape any astral Unicode symbols using ECMAScript 6 Unicode code point escape sequences.

-e, --escape-everything
Escape all the symbols in the output, even printable ASCII symbols.

-j, --json
Make sure the output is valid JSON. Hexadecimal character escape sequences and the \v or \0 escape sequences will not be used. Setting this flag enables the -d | --double-quotes and -w | --wrap settings.

-o, --object
Treat the input as a JavaScript object rather than a string. Accepted values are flat arrays containing only string values, and flat objects containing only string values.

-p, --pretty
Pretty-print the output for objects, using whitespace to make it more readable. Setting this flag enables the

-l, --lowercase-hex
Use lowercase for alphabetical hexadecimal digits in escape sequences. -o | --object setting.

-v, --version
Print jsesc's version.

-h, --help
Show the help screen.

EXIT STATUS
The jsesc utility exits with one of the following values:

0   jsesc successfully escaped the given string and printed the result.
1   jsesc wasn't instructed to escape anything (for example, the --help flag was set); or, an error occurred.

EXAMPLES

jsesc 'foo bar baz'
Print an escaped version of the given string.

echo 'foo bar baz' | jsesc
Print an escaped version of the string that gets piped in.
