jshint emitter emitter/emitter.js: line 15, col 61, Octal literals are not allowed in strict mode.

1 error

I receive the above message while running the linter jshint on my source code.

The offending line in the program is:

let pattern = new RegExp("^-(?=[gim]{1,3}$)(?!.*(.).*\1).*$");

jshint flags the error at \1 in the regular expression.

Is there any way to be rid of this message from jshint?

In node.js you have to antislash the antislash (one for node, one for the regex) due to how node.js is dealing with strings.

new RegExp('^-(?=[gim]{1,3}$)(?!.*(.).*\\1).*$');

    Not just in Node; in *any* JavaScript environment. – Pointy Apr 26 '19 at 12:34
  • It's basic JavaScript string syntax. I have no idea where the "octal literal" error is coming from, but the problem is that in any JavaScript string literal, backslashes ("antislash" is a better word!) have to be escaped. – Pointy Apr 26 '19 at 12:36

    I don't get an error from Node when I try the code in the OP. *edit* oh wait, I do in strict mode. I'm going to need more coffee ... – Pointy Apr 26 '19 at 12:37
