If the characters between the first three dashes are always numbers, you can do it like this:
variable = variable.replace(/^(\d+)-(\d+)-(\d+)-/, "$1/$2/$3/");
If they could be any arbitrary characters, then you can do it like this:
variable = variable.replace(/^([^-]+)-([^-]+)-([^-]+)-/, "$1/$2/$3/");

foo = foo.replace(/^(.*?)-(.*?)-(.*?)-(.*)$/, "$1/$2/$3/$4");

This should do the trick:
'12-16-23-some-words-now'.replace(/^(\d+)-(\d+)-(\d+)-/g, '$1/$2/$3/');
Are the first three always numbers?

Ah, @jfriend00 edited his answer just as I was answering. His won't necessarily replace the first three though, as he is missing the
^ operator.

yep. I'm generating these strings for one purpose where they cannot have backslashes, then use them to direct to a page, which requires the date (first three numbers) to be within backslashes.

+1 for noticing that it's actually three dashes that should be replaced, -1 for not noticing that there is no digit following the third dash :)
Find:
^([^-]*)-([^-]*)-([^-]*)-(.*)
Replace:
$1/$2/$3/$4

This one gets my vote. (
[^-]* is more precise and faster than .*?). Say what you mean - mean what you say! +1This exact structure can be fixed like this:
var string = "12-16-23-some-words-now";
var hyphensFormatted = string.substr(0, 9).replace(/-/g, "/");
var formattedString = hyphensFormatted + string.substr(9, string.length);
console.log(formattedString);
