replace multiple consecutive hyphens with one

Question

Is this possible in Javascript?

I have this from Java, but can not be used in Javascript.

s/-{2,}/-/g

Is there another way that works?

Answer 1

Yes it is. You can use the same regex with the Javascript replace() method.

s.replace(find, replacement)
// where 's' is your string object

Example:

var r = 'foo--bar---baz'.replace(/-{2,}/g, '-');
console.log(r); // "foo-bar-baz"

Answer 2

You can just do this:

var newStr = "hi--this is----good".replace(/-+/g,'-'); // hi-this is-good

-+ matches more than 1 - and replaces them with a single -

Your regex is also valid. Except you cannot use s modifier.
