I'm trying to split a string every n characters using a match function, but I figured that there are other uses to using a variable in a match function.

I know that the code

str.match(/.{0,3}/g);

will give me every three characters in a string, but

var n = 3;
str.match(/.{0,n}/g);

will not.

    You can always construct regular expressions with [`RegExp`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/RegExp). – Sebastian Simon Mar 14 '17 at 16:31

var n = 3;
str.match(new RegExp(".{0," + n + "}", "g"));
